Answer 1

Resposta:

4x – 1 = 7 2) 3x – 9 = 12 3) 3x + 2 = 4x + 9 4) 5x – 2 + 12 = 6x + 4 5) 2x – 6 = 16 6) 3x – 4 + 2 = 2x – 4 + 12 7) 4x – 7 = 2x – 8 8) 6x – 3 = 12 – 9x 9) x + 4 – 3x = 4 - 12x 10) 6x – 4 + 12 = 3 + 4x – 9 11) –5 = 3x + 4 – 12 - 9x 12) 3x + 5 - 2 = 2x + 12 13) 3(x + 2) = 15 14) –2 (-x + 2) = 3 (2x + 2) 15) 12x + 3 (x – 1) = -2(x -1) + 12 16) 2 (x - 1) = 0 17) 3 (x +2) = 15 18) 2 (x + 2) = 12 19) x = -3 (x – 4) 20) 2 (x + 5) = -3 (x – 5) 21) –2 (x + 4) = -21 + 9 (x – 1) 22) 5 (x – 4) = 1 + 9 (x – 1) 23) –5 (x – 4) + 4 = 2 (-2 x – 2) + 9 24) -2 (x – 5) + 3x = - (x + 2) – 2 25) - (x + 5) – 6 = -9 (x – 3) – 6 26) x - 7 + 2 (x – 4) = -3 (x + 2) – 8 27) 28) 29) 30) x 3 − 1 2 = − x 3
