10x - 40 + 15 = -15 (use distributive)
10x - 25 = -15. add integers on left

10x = 10 add 25 to both sides
x = 1 divide by 10

Answer:

x = 1

Step-by-step explanation:

Given

5(2x - 8) + 15 = - 15 ( subtract 15 from both sides )

5(2x - 8) = - 30 ( divide both sides by 5 )

2x - 8 = - 6 ( add 8 to both sides )

2x = 2 ( divide both sides by 2 )

x = 1

I'm thinking of a number. When I multiply by 8 and add –1, I get –17. What's my number?
frosja888 [35]

Say that you're thinking of number x

You multiply it by 8, and have 8x

You add -1 (i.e., you subtract 1) and have 8x-1

This equals -17, so you have

8x-1=-17

Add 1 to both sides

8x=-16

Divide both sides by 8:

x=-2

So, you were thinking of -2.
