$\; \; \;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\; \frac{2a+x}{6a} - \frac{5a-x}{8a}+1 = ? \\ \text{Multiplying the top and bottom of a fraction by the same constant does not change the fraction. To do this sum, you need the same denominator} \\ \text{on both fractions, needing the Lowest Common Multiple of the denominators. This is 24a. To get to this value, you need to multiply the} \\ \text{left fraction by 4 and the right fraction by 3.} \\ \frac{4(2a+x)}{4 \cdot6a} - \frac{3(5a-x)}{3 \cdot 8a}+1 = \frac{8a+4x}{24a} - \frac{15a-3x}{24a}+1 = \frac{x-7a}{24a}+1 \\ \\ \Rightarrow \frac{x-7a}{24a}=-1 \\ \Rightarrow x-7a = -24a \\ \Rightarrow x=-17a$ GeordieJake:)
