7x + 9 = 51 7x = 42 x = 42/7 = 6
7x is still the slope, no matter what x equals.
7x + 2 = 5,6
X=4.2666666666667
assuming the gap before x-2 is a +, then x+x-2=7x, so 2x-2=7x, so 5x=-2, so x=-.4
7x + 9 = 51 7x = 42 x = 42/7 = 6
If x=2, then 7x = 14 and if y=5 then 4y=20.
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
7x is still the slope, no matter what x equals.
7x + 2 = 5,6
X=4.2666666666667
assuming the gap before x-2 is a +, then x+x-2=7x, so 2x-2=7x, so 5x=-2, so x=-.4
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
its pretty easy: 3-2 = 1 so if u multiply 1 x 7x, it equals 7x
The math equation of X times 2 - 7x + 12 times 0 equals 2X - 7x.
7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1
x2-7x-18 (x-9) (x+2) x=9 x=-2 X= either 9 or -2
