Solve equation 1, x + 5 of X + 2 = 1.6 + 2 of X-12, 0.3 of 0.4 (x-3) - 0.04 of 0.1 x-0.2 = 1-2 of X-1 For a project, Party A will complete it in 20 days, Party B will complete it in 30 days, Party A will complete it in 5 days, and the rest will be completed by Party A and Party B in a few days?

Solve equation 1, x + 5 of X + 2 = 1.6 + 2 of X-12, 0.3 of 0.4 (x-3) - 0.04 of 0.1 x-0.2 = 1-2 of X-1 For a project, Party A will complete it in 20 days, Party B will complete it in 30 days, Party A will complete it in 5 days, and the rest will be completed by Party A and Party B in a few days?

1. X + 5 of X + 2 = 1.6 + 2 of x-110x + 2 (x + 2) = 16 + 5 (x-1) 10x + 2x + 4 = 16 + 5x-57x = 15x = 15 / 72, 0.3 of 0.4 (x-3) - 0.04 of 0.1x-0.2 = 1-2 of x-116 (x-3) - 3 (10x-30) = 12-6 (x-1) 16x-48-30x + 90 = 12-6x + 68x = 24x = 3 (1-5 / 20) / (1 / 20 + 1 / 30) = 9
