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

Addition to cancel -3: Given the equation z - 3 = 7, we want to isolate z to find its value. To do this, we add 3 to both sides of the equation to cancel out the -3 on the left side. z - 3 + 3 = 7 + 3Solve for z: After performing the addition, we get: z = 10Verify solution: We check our solution by substituting z = 10 back into the original equation to verify if it satisfies the equation. 10 - 3 = 7Solution verification: The left side of the equation simplifies to 7, which is equal to the right side of the equation. Therefore, our solution is correct.

Q. What value of

z

is a solution to this equation?

\newline

z - 3 = 7

\newline

Choices:

\newline

(A)

z = 10

\newline

(B)

z = 11

Addition to cancel $-3$ : Given the equation $z - 3 = 7$ , we want to isolate $z$ to find its value. $\newline$ To do this, we add $3$ to both sides of the equation to cancel out the $-3$ on the left side. $\newline$ $z - 3 + 3 = 7 + 3$
Solve for z: After performing the addition, we get: $\newline$ $z = 10$
Verify solution: We check our solution by substituting $z = 10$ back into the original equation to verify if it satisfies the equation. $10 - 3 = 7$
Solution verification: The left side of the equation simplifies to $7$ , which is equal to the right side of the equation. $\newline$ Therefore, our solution is correct.
