Reorder the terms:

3.7 + 1.2x = 2.2x + - 4.5

Reorder the terms:

3.7 + 1.2x = - 4.5 + 2.2x

Solving

3.7 + 1.2x = - 4.5 + 2.2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2.2x' to each side of the equation.

3.7 + 1.2x + - 2.2x = - 4.5 + 2.2x + - 2.2x

Combine like terms: 1.2x + - 2.2x = - 1x

3.7 + - 1x = - 4.5 + 2.2x + - 2.2x

Combine like terms: 2.2x + - 2.2x = 0.0

3.7 + - 1x = - 4.5 + 0.0

3.7 + - 1x = - 4.5

Add '-3.7' to each side of the equation.

3.7 + - 3.7 + - 1x = - 4.5 + - 3.7

Combine like terms: 3.7 + - 3.7 = 0.0

0.0 + - 1x = - 4.5 + - 3.7

-1x = - 4.5 + - 3.7

Combine like terms: - 4.5 + - 3.7 = - 8.2

-1x = - 8.2

Divide each side by '-1'.

x = 8.2

Simplifying

x = 8.2
