Answer:

X = 6x

Explanation:

Simplifying

X + 9 + -0.8x = 5.2x + 17 + -8

Reorder the terms:

9 + X + -0.8x = 5.2x + 17 + -8

Reorder the terms:

9 + X + -0.8x = 17 + -8 + 5.2x

Combine like terms: 17 + -8 = 9

9 + X + -0.8x = 9 + 5.2x

Add '-9' to each side of the equation.

9 + X + -9 + -0.8x = 9 + -9 + 5.2x

Reorder the terms:

9 + -9 + X + -0.8x = 9 + -9 + 5.2x

Combine like terms: 9 + -9 = 0

0 + X + -0.8x = 9 + -9 + 5.2x

X + -0.8x = 9 + -9 + 5.2x

Combine like terms: 9 + -9 = 0

X + -0.8x = 0 + 5.2x

X + -0.8x = 5.2x

Solving

X + -0.8x = 5.2x

Solving for variable 'X'.

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

Add '0.8x' to each side of the equation.

X + -0.8x + 0.8x = 5.2x + 0.8x

Combine like terms: -0.8x + 0.8x = 0.0

X + 0.0 = 5.2x + 0.8x

X = 5.2x + 0.8x

Combine like terms: 5.2x + 0.8x = 6x

X = 6x

Simplifying

X = 6x
