Solve the equation below.
3/2x - 2.2 = 2(0.7x - 1)

3/2x-2.2=2(0.7x-1) convert the decimal into a fraction.
3/2x - 11/5 = 2(0.7 x - 1) distribute 2 through the parentheses.
3/2 x - 11/5 = 1.4 x - 2 convert the decimal into a fraction.
3/2 x - 11/5 = 7/5 x - 2 multiply both sides of the equation by 10.
15x - 22 = 14 x - 20 move the variable to the left-hand side and change its sign.
15x - 22 - 14 x = -20 move the constant to the right-hand side and change its sign.
15 x - 14x = -20 + 22 collect like terms.
x = -20 + 22 calculate the sum.
x = 2 solution.

The first one minimumi hope my answer you.
