Question

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

Answer 1

Answer:

6

Step-by-step 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

$\frac{ - 5x}{ - 5} = \frac{ - 30}{ - 5}$

Calculate

$x = 6$

Hope this helps...

Best regards!!

Answer 2

Answer:

x = 6

Step-by-step 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
