5x - 15 = 20 the first step in solving this equation is subtract 15 from both sides of the equation. add 15 to both sides of the equation. divide both sides of the equation by 5. add -20 to both sides of the equation.

Honestly the answer might be divide by 5. It may not be right tho. Sorry if It is wrong.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

- 70

this is the answer for you hope it
