Answer:

<h2>6</h2>

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:

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
