.......expand the brackets by taking the 2 on the outside and multiplying everything inside

......now group the x's and simplify

........get the x's alone on the right side by subtracting the 2, since this is an equation, we must subtract the 2 from the other side as well

........divide both sides by 5

........multiply through by 4 to get rid of the fraction-10 = 4 - 7x/4

*7x/4 is a fraction

now solve as i did above, remember your objective is to get the x on one side of the equation by itself
