Question

Simplify the expression. NEED WORK SHOWN!!

5x - 3y - 2(4x - y)

Answer 1

5x + 4x + -3y + -2y = 0

9x + -3y + -2y = 0

9x + -5y = 0

9x + -5y = 0

Solving for variable 'x'.

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

Add '5y' to each side of the equation.

9x + -5y + 5y = 0 + 5y

Combine like terms: -5y + 5y = 0

9x + 0 = 0 + 5y

9x = 0 + 5y

Remove the zero:

9x = 5y

Divide each side by '9'.

x = 0.5555555556y

Simplifying

x = 0.5555555556y

Answer 2

5x -3y -2(4x-y)
= 5x -3y -8x -2y
= -3x -5y
= +15xy = 15xy
