Answer 2

Let's solve each equation step by step:

(1) -1.4(x - 6) = 7(4x + 1.2)

Expand the equation: -1.4x + 8.4 = 28x + 8.4

Combine like terms: -1.4x - 28x = -8.4 + 8.4 -29.4x = 0

Divide both sides by -29.4: x = 0

Therefore, the solution for equation (1) is x = 0.

(2) 2.6(0.4x - 1.4) = -3.9(1.2x - 0.9)

Expand the equation: 1.04x - 3.64 = -4.68x + 3.51

Combine like terms: 1.04x + 4.68x = 3.51 + 3.64 5.72x = 7.15

Divide both sides by 5.72: x = 7.15 / 5.72 x ≈ 1.25

Therefore, the solution for equation (2) is x ≈ 1.25.
