Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
n= -2
2x+3 = 7 2x = 7-3 2x = 4 x = 2
(7)-(-3)+(16)-(8) = 18
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
x=-2
n= -2
2x+3 = 7 2x = 7-3 2x = 4 x = 2
(7)-(-3)+(16)-(8) = 18
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
you need to find the value of X first before you can solve this equation
(3x - 7)(2x + 9) = 0 x = 7/3 or -9/2
If you mean: 3+5x+7 = 70 then the value of x is 12
-3+x=7. x=10
u = 7 + 2 + (4 - 5) = 9 + (-1) = 8
