Question

solve the equation below, where there are z terms on both sides of the equation. whats the value of z? add 4z to both sides, then rewrite the equation to represent the remaining values. 15 - 4z = 8 + 3z + 4z + 4z \square = \square

Explanation:

Step1: Simplify Left Side

Add \( -4z + 4z \) on left, so \( 15 - 4z + 4z = 15 \).

Step2: Simplify Right Side

Add \( 3z + 4z \) on right, so \( 8 + 3z + 4z = 8 + 7z \).

Answer:

\( 15 = 8 + 7z \) (Then to solve for \( z \), subtract 8: \( 7 = 7z \), divide by 7: \( z = 1 \), but for the blanks: left is 15, right is \( 8 + 7z \))
