23 = 7x + 7x - 5 = 14x - 5
14x = 23 + 5 = 28
x = 28/14 = 2
7x2 plus 7x5 = 49
7x = 21 x = 3
-46 = 3x + 7x
The answer is nine. Seriously. Here is my work if you don't believe me: 68=8x+23+4x-7x 68=8x-7x+23+4x 68=x+23+4x 68=x+4x+23 68=5x+23 68-23=5x 45=5x x=45/5 x=9
It is 9x
7x2 plus 7x5 = 49
7x = 21 x = 3
23
2x + 2 + 5x = 23 2x +5x = 23 -2 7x = 21 X = 3
-46 = 3x + 7x
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
The answer is nine. Seriously. Here is my work if you don't believe me: 68=8x+23+4x-7x 68=8x-7x+23+4x 68=x+23+4x 68=x+4x+23 68=5x+23 68-23=5x 45=5x x=45/5 x=9
It is 9x
13x
x=6
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
7x + y = 4y = 4 - 7x
