Cross multiply: 4 * 20 = x * 8 Simplifying 4 * 20 = x * 8 Multiply 4 * 20 80 = x * 8 Reorder the terms for easier multiplication: 80 = 8x Solving 80 = 8x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8x' to each side of the equation. 80 + -8x = 8x + -8x Combine like terms: 8x + -8x = 0 80 + -8x = 0 Add '-80' to each side of the equation. 80 + -80 + -8x = 0 + -80 Combine like terms: 80 + -80 = 0 0 + -8x = 0 + -80 -8x = 0 + -80 Combine like terms: 0 + -80 = -80 -8x = -80 Divide each side by '-8'. x = 10 Simplifying x = 10
