When you type 1/2x I don't know if you mean $\frac{1}{2x}$ or $\frac{1}{2} x.$ I expect you mean $\frac{1}{2} x$ so you should type (1/2) x. The subject line of your email was "Simultaneous equations with fractions" so I expect it is the fractions that are creating your dilemma I would start be eliminating the fractions. For example with your second equation \[8x + \frac25 y = 102\] the only denominator is 5 so I would multiply each side by 5 and simplify to get \[40x + 2y = 510.\] This equation is equivalent to your second equation but has no fractions. In your first equation there are two denominators 2 and 3 so you can multiply by 2 and then by 3 to find an equivalent equation with no fractions but you can accomplish this in one step by multiplying both sides by $2 \times 3 = 6.$ Try it. You should now have two equations with no fractions. Can you solve them? Write back if you need more assistance,
