Answer:
34
Step-by-step explanation:
Given that
2x - 7 = 9 ← solve for x
Add 7 to both sides
2x = 16 ( divide both sides by 2 )
x = 8
Substitute x = 8 into 5x - 6
5x - 6 = (5 × 8) - 6 = 40 - 6 = 34
z + 93 = 180
z = 87
Answer z = 87
Here are the answer for x and y, in case you need them.
x = 2* 93 - 112
x = 186 - 112
x = 74
y = 2 * 80 - x
y = 160 - 74
y = 86
Not sure either I need the question
