Which equation has the solution x=3 ? 8x-4=-20 6x+7=64 4x-7=5 8x-1=87

Substitute x=3: Let's start by substituting x=3 into the first equation 8x-4=-20 and see if it holds true. Calculation: 8(3) - 4 = 24 - 4 = 20 Now, let's compare this result with the right side of the equation. 20 ≠ -20Check first equation: Since the first equation does not hold true for x=3, let's try the second equation 6x+7=64. Calculation: 6(3) + 7 = 18 + 7 = 25 Now, let's compare this result with the right side of the equation. 25 ≠ 64Check second equation: The second equation also does not hold true for x=3, so let's try the third equation 4x-7=5. Calculation: 4(3) - 7 = 12 - 7 = 5 Now, let's compare this result with the right side of the equation. 5 = 5 This equation holds true for x=3.Check third equation: Since we have found an equation that holds true for x=3, there is no need to check the fourth equation. However, for completeness, let's check the fourth equation 8x-1=87. Calculation: 8(3) - 1 = 24 - 1 = 23 Now, let's compare this result with the right side of the equation. 23 ≠ 87

Q. Which equation has the solution

x=3

\newline

8 x-4=-20

\newline

6 x+7=64

\newline

4 x-7=5

\newline

8 x-1=87

Substitute $x=3$ : Let's start by substituting $x=3$ into the first equation $8x-4=-20$ and see if it holds true. $\newline$ Calculation: $8(3) - 4 = 24 - 4 = 20$ $\newline$ Now, let's compare this result with the right side of the equation. $\newline$ $20 \neq -20$
Check first equation: Since the first equation does not hold true for $x=3$ , let's try the second equation $6x+7=64$ . $\newline$ Calculation: $6(3) + 7 = 18 + 7 = 25$ $\newline$ Now, let's compare this result with the right side of the equation. $\newline$ $25 \neq 64$
Check second equation: The second equation also does not hold true for $x=3$ , so let's try the third equation $4x-7=5$ . $\newline$ Calculation: $4(3) - 7 = 12 - 7 = 5$ $\newline$ Now, let's compare this result with the right side of the equation. $\newline$ $5 = 5$ $\newline$ This equation holds true for $x=3$ .
Check third equation: Since we have found an equation that holds true for $x=3$ , there is no need to check the fourth equation. However, for completeness, let's check the fourth equation $8x-1=87$ . $\newline$ Calculation: $8(3) - 1 = 24 - 1 = 23$ $\newline$ Now, let's compare this result with the right side of the equation. $\newline$ $23 \neq 87$
