To solve the equation 3.1(x+2)1.5x=5.2(x4):

Distribute the terms inside the parentheses: 3.1x + 6.2  1.5x = 5.2x  20.8

Combine like terms: (3.1x  1.5x) + 6.2 = 5.2x  20.8 1.6x + 6.2 = 5.2x  20.8

Move the variable terms to one side and the constant terms to the other side: 6.2 + 20.8 = 5.2x  1.6x 27 = 3.6x

Divide both sides by 3.6: x = 27 / 3.6 x = 7.5
