3x+5 = 26 Subtract 5 from both sides: 3x = 21 Divide both sides by 3 to find the value of x: x = 7
23
-3x + 5 = 20 -3x = 15 x = -5
x = -8
7x = 3x - 12 4x=-12 x=-3
3x+5 = 26 Subtract 5 from both sides: 3x = 21 Divide both sides by 3 to find the value of x: x = 7
3
x = -8

x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
3x + 5 = 20 Subtract '5' from both sides 3x = 15 Divide both sides by '3' x = 5 The answer!!!!!
-3x + 5 = 20 -3x = 15 x = -5
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
x = 6
x = -8
7x = 3x - 12 4x=-12 x=-3
x = 5, y = -1
