2X - 4 = - 10
add 4 to each side
2X - 4 + 4 = - 10 + 4
2X = - 6
divide each side by 2
X = - 3
check in original equation
2(-3) - 4 = - 10
- 6 - 4 = - 10
- 10 = - 10
checks
2x + 10 = 182x = 8x = 4

If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.
5x+2=2x-10 x=-4
2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
4 - 2x = 10 -2x = 10-4 -2x = 6 -x = 3 x = -3
2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
2x + 10 = 182x = 8x = 4

If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.
2x+4 = -16 2x = -16-4 2x = -20 x = -10
2x - 6 = 4 2x = 4 + 6 = 10 x = 10/2 = 5 ∴ x = 5
x=7.
5x+2=2x-10 x=-4
2x -6 = 4 then 2x = 4 +6 x=10/2 = 5
2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20
