The general form is . It requires that A and B be greater than 1 (not fractions or decimals) and A is positive. This equation is 2x + y = 6 is almost already in the form. Subtract C to both sides to make it general form. 2x + y - 6 =0. The coefficients of the x and y are greater than 1 and 2 is positive. This meets the requirements.
3c/5-1/2=-31/2 Add 1/2 both sides +1/2 +1/2 3c/5=-30/2 Then simplify the fraction (5)3c/5=-15(5) Multiply 5 both sides 3c=75 Finally, divide by 3 both sides c=25 So the answer to your question is E.
