5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
-2x+14=20 -2x=20-14 -2x=6 -2x/-2=6/-2 x=-3
In the straight line equation of y = 2x+14 the slope or gadient is 2 and the y intercept is 14
X2 + 2X - 14 = 6X2 + 2X - 8 = 0what two products of - 8 = 2 ?(X +4)(X - 2)=========X = - 4X = 2
If -2x +14 = 0, -2x = -14, or x = 7.
-2x+14=20 x=-3
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4

2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)

A Letter.14-2x=3x+113-2x=3x3=5xX=0.6
14x - 14 = 2x + 46 14x - 2x = 46 + 14 12x = 60 x = 5
5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
x+2x+14=5x+214-2=5x+2x+x10=8x10/8=xx=5/4 ans.
3x+10=14+2x so subtract 2x from both sides x+10=14 so x=14-10 so x = 4
