Solve ( 0.5x + 1.2 = 0.3x - 0.4 ) Multiply by 10: ( 5x + 12 = 3x - 4 ) → ( 2x = -16 ) → ( x = -8 ).

By the end of this article, you will be able to systematically solve any single-variable equation, no matter how tangled it initially appears.

Left: (-x + 8) Right: (2 - x)

No fractions. Kael breathed for the first time in hours.

Fractions terrify many, but they obey the same rules. Two powerful strategies:

Look at the left side of the equals sign. Can you merge any numbers or variables? Do the same for the right side.
