15x - 30 = -15 (Solve for X and show work)

x = 1

Step-by-step explanation:

15x - 30 = -15

+30. +30

15x = 15

15. 15

x = 1

check

15(1) - 30 = -15

15 - 30 = - 15

x =

Step-by-step explanation:

15x - 30 = -15

Add 30 to both sides

15x + 30 = 15

15x = 15

Divide both sides by 15

15x / 15 = 15

x = 1

thats not a system of equations, that is a solution

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
