4x - 7 = 5 + 7x x = -4
7x + 5y 7(3) + 5(2) 21 + 10 = 31
7x-1=2x+5 7x-2x=5+1 5x=6 x=6/5=1.2
If x=2, then 7x = 14 and if y=5 then 4y=20.
7x + 10 = -7x - 60 Add 7x to both sides: 14x + 10 = -60 Subtract 10 from both sides: 14x = -70 Divide both sides by 14: x = -5
7
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
7x is still the slope, no matter what x equals.
4x+5=7x-8 the ansewr is 3.25
23 = 7x + 7x - 5 = 14x - 5 14x = 23 + 5 = 28 x = 28/14 = 2
x = -5
4x - 7 = 5 + 7x x = -4
x=6
The value of x is 1
X=2
10x + 5 which is also equal to 5(2x + 1)
