Answer:
x = 4
Step-by-step explanation:
To find what value makes the expression -1 - 2x = 7 - 4x true, we can solve for x in the expression.
-1 - 2x = 7 - 4x
Add 1 to both sides.
-2x = 8 - 4x
Add 4x to both sides.
2x = 8
Divide both sides by 2.
x = 4
So after solving for x in the expression, we have found the x = 4. So the value of 4 for x would make the expression true.
I hope this helps. Happy studying.
