Answer:
The value of z is -7
Explanation:
To solve this problem, we will follow the step below;
1/4 z = -7/8 + 1/8 z
Subtract 1/8 z from both-side of the equation
1/4 z - 1/8 z = -7/8
2z - z /8 = -7/8
z/8= -7/8
Multiply both-side of the equation by 8
z/8 × 8 = -7/8 × 8
At the left-hand side of the equation 8 will cancel-out 8 leaving us with just z while on the right-hand side of the equation 8 will also cancel-out 8 leaving us with negative seven
z = -7
The value of z is -7
