29 — 6x=5(1 – 6x) Please show me the steps

Lady bird [3.3K]

Answer:

x= -1

Step-by-step explanation:

START 29 - 6x = 5(1 - 6x)

1. Distribute

29 - 6x = 5 - 30x

2. Isolate the variable

~ 2a. Add 30x to both sides

29 - 6x + 30x = 5 - 30x + 30x

~ 2b. Subtract 29 from both sides

29 - 29 - 6x + 30x = 5 - 29 - 30x + 30x

3. Simplify

24x = -24

4. Solve

x = -1

END
