You solve this system using substitution ..since there is already an equation that just a has a variable = , you plug ithat in the other equation.... so 1/2x goes where the y is ....1/2 of 3x is 1.5 x which you add to 2x and you get 3.5 x = 28 ..you divide by 3.5 on both sides and get x = 8 ..you then go back into the equation and plug in 8 for x and solve for y ..which 1/2(8) = 4 so y is 4 ...and that gives you the coordinates of your answer .....
