Step-by-step explanation:

Answer 2

Answer:  

Simplifying

2x + -10y = 15

Solving

2x + -10y = 15

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10y' to each side of the equation.

2x + -10y + 10y = 15 + 10y

Combine like terms: -10y + 10y = 0

2x + 0 = 15 + 10y

2x = 15 + 10y

Divide each side by '2'.

x = 7.5 + 5y

Simplifying

x = 7.5 + 5yStep-by-step explanation:
