Question

What is the solution to this equation 10x-15x+5=-45+20

Answer 1

x = 6

Explanation:

10x - 15x + 5 = -45 + 20

→ Simplify the 10x - 15x

-5x + 5 = -45 + 20

→ Simplify the -45 + 20

-5x + 5 = -25

→ Minus 5 both sides from to isolate -5x

-5x = -30

→ Divide by -5 from both sides from to isolate x

x = 6

Answer 2

6

Explanation:

`10x - 15x + 5 = - 45 + 20`

Collect like terms

`- 5x + 5 = - 45 + 20`

Calculate the sum

`- 5x + 5 = - 25`

Move constant to RHS and change its sign

`- 5x = - 25 - 5`

Calculate

`- 5x = - 30`

Divide both sides of the equation by -5

`( - 5x)/( - 5) = ( - 30)/( - 5)`

Calculate

`x = 6`

Hope this helps...
