Answer:
4:x:9::13:3
Step-by-step explanation:
Simplifying 13 = 3(x + -4) + -1(x + -9) Reorder the terms: 13 = 3(-4 + x) + -1(x + -9) 13 = (-4 * 3 + x * 3) + -1(x + -9) 13 = (-12 + 3x) + -1(x + -9) Reorder the terms: 13 = -12 + 3x + -1(-9 + x) 13 = -12 + 3x + (-9 * -1 + x * -1) 13 = -12 + 3x + (9 + -1x) Reorder the terms: 13 = -12 + 9 + 3x + -1x Combine like terms: -12 + 9 = -3 13 = -3 + 3x + -1x Combine like terms: 3x + -1x = 2x 13 = -3 + 2x Solving 13 = -3 + 2x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. 13 + -2x = -3 + 2x + -2x Combine like terms: 2x + -2x = 0 13 + -2x = -3 + 0 13 + -2x = -3 Add '-13' to each side of the equation. 13 + -13 + -2x = -3 + -13 Combine like terms: 13 + -13 = 0 0 + -2x = -3 + -13 -2x = -3 + -13 Combine like terms: -3 + -13 = -16 -2x = -16 Divide each side by '-2'. x = 8 Simplifying x = 8 (or)
