Hi Dear Kate
■ 10x + 15 = 5x - 10
■ 10 x - 5x = - 10 - 15
■ x ( 10 - 5 ) = - 25
■ 5x = -25
■ x = -25 / 5
■ x = -5
Good Luck Katy ♣

10x + 15 = 5x - 10
1. Combine like terms
5x = -25
2. Solve for X
x = -5

10x + 15 = 5x - 10
10x + 15 - 5x = 5x - 10 - 5x
5x + 15 = - 10
5x + 15 - 15 = - 10 - 15
5x = - 25
5x/5 = - 25/5
x = - 5
The answer is x = -5
Insert the x value into the equation
- - - - - - - - - - - - - - - - - - - - - -
Check
10x+ 15 = 5x = 10
10(- 5) + 15 = 5(- 5) - 10
- 50 + 15 = - 25 - 10
- 35 = - 35

10X + 15 = 5X - 10 = 2X + 5, the x multiply and the digits are the equation point. So the answer is 2x + 5. thank you.

x=-5
(10x + 15 = 5x - 10
10x-5x=-10-15
x(10-5)=-25
x*5=-25
5*x=-25
x=-25/5
x=-(5*5/5)
x=-5)
