$${\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{7}}{\mathtt{\,\times\,}}{\mathtt{x}} = {\mathtt{60}}$$how do you find the solution to an equation
Get all the x terms on one side and then get x on its own.
In the example you gave, we have 5x + 7x = 60.
To get x on its own, we factorise so
x(5+7)=60
Now x is on its own and we have $${\frac{{\mathtt{60}}}{\left({\mathtt{5}}{\mathtt{\,\small\textbf+\,}}{\mathtt{7}}\right)}} = {\mathtt{5}}$$
x=5
