Simplifying 0.1(t + 0.5) + 0.2t = 0.3(t + 0.4) Reorder the terms: 0.1(0.5 + t) + 0.2t = 0.3(t + 0.4) (0.5 * 0.1 + t * 0.1) + 0.2t = 0.3(t + 0.4) (0.05 + 0.1t) + 0.2t = 0.3(t + 0.4) Combine like terms: 0.1t + 0.2t = 0.3t 0.05 + 0.3t = 0.3(t + 0.4) Reorder the terms: 0.05 + 0.3t = 0.3(0.4 + t) 0.05 + 0.3t = (0.4 * 0.3 + t * 0.3) 0.05 + 0.3t = (0.12 + 0.3t) Add '-0.3t' to each side of the equation. 0.05 + 0.3t + -0.3t = 0.12 + 0.3t + -0.3t Combine like terms: 0.3t + -0.3t = 0.0 0.05 + 0.0 = 0.12 + 0.3t + -0.3t 0.05 = 0.12 + 0.3t + -0.3t Combine like terms: 0.3t + -0.3t = 0.0 0.05 = 0.12 + 0.0 0.05 = 0.12 Solving 0.05 = 0.12 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
