SO SIMPLE

Simplifying x + 7.05 = 45.3 reorder the terms: 7.05 + x = 45.3 solving 7.05 + x = 45.3 solving for variable 'x'. move all terms containing x to the left, all other terms to the right. add '-7.05' to each side of the equation. 7.05 + -7.05 + x = 45.3 + -7.05 combine like terms: 7.05 + -7.05 = 0.00 0.00 + x = 45.3 + -7.05 x = 45.3 + -7.05 combine like terms: 45.3 + -7.05 = 38.25 x = 38.25 simplifying x = 38.25
