-0.72 + 1.24z = 0.7(2 + z)
-0.72 + 1.24z = (2 * 0.7 + z * 0.7)
-0.72 + 1.24z = (1.4 + 0.7z)

Solving
-0.72 + 1.24z = 1.4 + 0.7z

Solving for variable 'z'.

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

Add '-0.7z' to each side of the equation.
-0.72 + 1.24z + -0.7z = 1.4 + 0.7z + -0.7z

Combine like terms: 1.24z + -0.7z = 0.54z
-0.72 + 0.54z = 1.4 + 0.7z + -0.7z

Combine like terms: 0.7z + -0.7z = 0.0
-0.72 + 0.54z = 1.4 + 0.0
-0.72 + 0.54z = 1.4
