7x + 8 = 11x + 3, solve for x
subtract 7x from both sides
8 = 11x - 7x + 3
8 = 5x + 3
subtract 3 from both sides
5 = 5x
divide both sides by 5
1 = x.
11x - 21 = 7x + 3 4x = 24x = 6
11x+9=7x+21 11x-7x=4 4x+9=21 21-9=12 4x=12 12 divided by 4= 3 x=3
x=3 actually its 7
x=3
-(5x + 3)(7x - 2)
2x2 + 11x + 15 = (x + 3)(2x + 5).
-7x - 2y = -3
The answer to the math problem -3 7x plus 7 is x equals 1/3.
3+3x+7x=13 3x+7x=10 10x=10 x=1
Subtract by 7x and divide by 2.
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
7x + y + 3 = y7x + 3 = 07x = -3x = -3/7
