What value of z is a solution to this equation? z - 7 = 3 Choices: (A)z = 10 (B)z = 11

Addition to cancel -7: To solve for z, we need to isolate z on one side of the equation. We can do this by adding 7 to both sides of the equation to cancel out the -7 on the left side. Calculation: z - 7 + 7 = 3 + 7Result after addition: After performing the addition, we get the following result: z = 10Substitute z = 10: Now we need to check if our solution is correct by substituting z back into the original equation. Substitute z = 10 into z - 7 = 3: 10 - 7 = 3Result after substitution: After performing the subtraction, we get the following result: 3 = 3 This confirms that our solution is correct because both sides of the equation are equal.

Q. What value of

z

is a solution to this equation?

\newline

z - 7 = 3

Addition to cancel $-7$ : To solve for $z$ , we need to isolate $z$ on one side of the equation. We can do this by adding $7$ to both sides of the equation to cancel out the $-7$ on the left side. $\newline$ Calculation: $z - 7 + 7 = 3 + 7$
Result after addition: After performing the addition, we get the following result: $\newline$ $z = 10$
Substitute $z = 10$ : Now we need to check if our solution is correct by substituting $z$ back into the original equation. $\newline$ Substitute $z = 10$ into $z - 7 = 3$ : $\newline$ $10 - 7 = 3$
Result after substitution: After performing the subtraction, we get the following result: $\newline$ $3 = 3$ $\newline$ This confirms that our solution is correct because both sides of the equation are equal.
