add 3x and 5x together to make 8x. Then your equation will be 8x=32. Lastly, divide 8 to both sides which will make x=4.
23
x=7
-3x + 5 = 20 -3x = 15 x = -5
x = -8
7x = 3x - 12 4x=-12 x=-3

x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
x = 6
x = 5, y = -1
X=5
