3x + 4 = 37
Subtracting 4 from both sides
3x + 4 - 4 = 37 - 4
3x = 33
Dividing both sides by 3, we get
x = 11
3x+7=37 -7 -7 3x=30 /3 /3 x=10
4
x=5
23
3
x=7
x = -8
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
-3x + 5 = 20 -3x = 15 x = -5
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
x = -8
x = 6
