Answer:
X = 6x
Step-by-step 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
