2.66 + 1.4z = 0.7(-1.2 + z)
2.66 + 1.4z = (-1.2 * 0.7 + z * 0.7)
2.66 + 1.4z = (-0.84 + 0.7z)

Solving
2.66 + 1.4z = -0.84 + 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.
2.66 + 1.4z + -0.7z = -0.84 + 0.7z + -0.7z

Combine like terms: 1.4z + -0.7z = 0.7z
2.66 + 0.7z = -0.84 + 0.7z + -0.7z

Combine like terms: 0.7z + -0.7z = 0.0
2.66 + 0.7z = -0.84 + 0.0
2.66 + 0.7z = -0.84
