23 = 7x + 7x - 5 = 14x - 5 14x = 23 + 5 = 28 x = 28/14 = 2
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
7x is still the slope, no matter what x equals.
4x+5=7x-8 the ansewr is 3.25
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
23 = 7x + 7x - 5 = 14x - 5 14x = 23 + 5 = 28 x = 28/14 = 2
11X - 23 = 7X + 5 subtract 7X from both sides 11X - 7X - 23 = 7X - 7X + 5 4X - 23 = 5 add 23 to both sides 4X - 23 + 23 = 5 + 23 4X = 28 divide both sides integers by 4 (4/4)X = 28/4 X = 7 --------------------check in original equation 11(7) - 23 = 7(7) + 5 77 - 23 = 49 + 5 54 = 54 checks
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
2x + 2 + 5x = 23 2x +5x = 23 -2 7x = 21 X = 3
7x is still the slope, no matter what x equals.
4x+5=7x-8 the ansewr is 3.25
4x - 7 = 5 + 7x x = -4
x = 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
x=6
7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
