Answer:
x = -3
Step-by-step explanation:
What you do is get x by itself.
1/4(8x - 4) = 5x + 8 Distribute 1/4 to 8x and -4.
2x - 1 = 5x + 8 Subtract 5x on both sides.
-3x -1 = 8 Add -1 to both sides.
-3x = 9 Divide -3 on both sides.
x = -3
Answer: - 3
Step-by-step explanation:
Expand the brackets
It will give: 2x - 1 = 5x + 8
Collect like terms: 2x - 5x = 1 + 8
- 3x = 9
Divide both sides by - 3
x = -3
