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
X2 + 2X - 14 = 6X2 + 2X - 8 = 0what two products of - 8 = 2 ?(X +4)(X - 2)=========X = - 4X = 2
What is X if 2x + 4 = 36 What is X ? 2x + 4 = 36
If X = 4 then 2X = 2 x 4, which is 8
