Question
Lesson 3.4: Solving Complex 1-Variable EquationsSolve each equation.1a. 3x + 4 + 2x + 5 = 341b. 2(x + 1) + 4 = 122a. 1/2(x + 8) - 15 = -32b. 2x - 5 + 3x + 8 = 183a. -185 = -3r - 4(-5r + 8)3b. -5t - 2(5t + 10) = 1004a. -4b - 4(-6b - 8) = 1724b. -3p + 2(5p - 12) = -735a. -3f + 3(-3f + 5) = -815b. -43 = -5c + 4(2c + 7)6a. -5s + 3(5s + 2) = 1266b. 4d + 2(4d + 7) = -1067a. 103 = -2u + 3(-3u + 5)7b. -2n + 2(3n + 14) = -208a. -11 = 5y + 4(-y - 4)8b. -5a - 2(-7a - 10) = 1289a. 1/2(c + 5) - 10 = -49b. -4f + 1/2(4f - 5) = -1910a. 2(v + 4) + 6 = 2410b. -9 = 6h + 3(-h - 3)11a. -6p - 8(4p + 8) = 9811b. 7c + 3(3c + 5) = -10312a. -4s + 2(4s + 1) = 12512b. -3n + 3(4n + 15) = -21
