The equation can be solved by isolating the variables from the numbers. The answer would be 4x = 8, which equals 2.
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
(2, -1)
x=10
3x + 7 = 46 is an equation. It can be solved as follows: 3x = 39 so x = 13
3x + 2 = -10 3x = -12 x = -4
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
-2
3+3x+7x=13 3x+7x=10 10x=10 x=1
x = 2
The answer is -7
(4, -1)
