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

First, distribute the -1.4 on the left side:

-1.4x + 8.4 = 28x + 8.4

Next, move all the x terms to one side and the constant terms to the other side:

-1.4x - 28x = -8.4 + 8.4

-29.4x = 0

Finally, solve for x:

x = 0

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

First, simplify inside the parentheses:

2.6(-1) = 3.9(1.2x - 0.9)

-2.6 = 4.68x - 3.51

Next, move all the x terms to one side and the constant terms to the other side:

4.68x = -2.6 + 3.51

4.68x = 0.91

Finally, solve for x:

x ≈ 0.194

Therefore, the solutions for the given equations are:

1) x = 0
2) x ≈ 0.194
