X=8 is the correct answer :)
Answer:
X=4.2
Step-by-step explanation:
Simplifying 8x + -4 = 3x + 17 Reorder the terms: -4 + 8x = 3x + 17 Reorder the terms: -4 + 8x = 17 + 3x Solving -4 + 8x = 17 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. -4 + 8x + -3x = 17 + 3x + -3x Combine like terms: 8x + -3x = 5x -4 + 5x = 17 + 3x + -3x Combine like terms: 3x + -3x = 0 -4 + 5x = 17 + 0 -4 + 5x = 17 Add '4' to each side of the equation. -4 + 4 + 5x = 17 + 4 Combine like terms: -4 + 4 = 0 0 + 5x = 17 + 4 5x = 17 + 4 Combine like terms: 17 + 4 = 21 5x = 21 Divide each side by '5'. x = 4.2 Simplifying x = 4.2
