Answer:
x = - 7
Step-by-step explanation:
Given
- 5(x - 2) - (x + 2) = 50 ← distribute parenthesis on left side
- 5x + 10 - x - 2 = 50, that is
- 6x + 8 = 50 ( subtract 8 from both sides )
- 6x = 42 ( divide both sides by - 6 )
(-5x - 10) - 2x = 50
-7x - 10 = 50
+10 +10
-7x = 60
-7x/7 = 60/7
x=8.57142857143 or 60/7
You first distribute the -5 to X and 2 then add x and 2. Then add 10 on both sides. Next divided each side by POSITIVE 7 and decimal or fraction is ur final answer
What i would do is multiply both sides by 2z + 1
so you get z-6=20z+10
-19z=16
z=-16/19
i think the answer is 1/9
