3x+5=4-2x+6
5x=4-1
5x=3
x=3/5
Collect the like terms;42x-23 = 940Add 23 to both sides;42x = 963Divide both sides by 42;x = 963/42
-1/19=x
x=7

It is 14*(3x + 2y)
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
3x plus 5 equals 20: 3x + 5 = 20 3x + 5 - 5 = 20 - 5 3x = 15 3x/3 = 15/3 x = 5
-3x + 5 = 20 -3x = 15 x = -5
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
x = 6
