7 x - 4 x + 2 x+5 = 2 x + 14 --- (1)
Shift those terms containing "x" on left side and constants on other side
7 x - 4 x + 2 x - 2 x = 14 - 5
We will get
3 x = 9
Divide both sides by "3" we get;
x = 3

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
