Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y
I assume you wish to simplify the expression (x - 2)/(3x + 9) . (2x + 6)/(2x - 4) = (x - 2)(2x + 6) / [(3x + 9)(2x - 4)] = 2(x - 2)(x + 3) / [6(x + 3)(x - 2)] = 1/3.
Without parentheses, 3 x 4 = 12 2x + 12 factors to 2(x + 6)
you need to reorder the problem by manipulating the numbers -2x-7=-x+13 group your variables and constants thus -x-2x=7+13 simplify -3x=20 simplify again x=-20/3
