2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
2x + 4 = y ...............2x + 4 = y ....................2x + 4 = y .............2*(-6)+ 4 = y x - y = 2 .......<=> ...x - 2x - 4 = 2 .....<=> ...x = -6......... <=>.... x = -6 ..............<=> y = - 8 x = - 6
2x+4 = -16 2x = -16-4 2x = -20 x = -10
2X - 2 = 4X + 6 subtract 2x from both sides - 2 = 2X + 6 subtract 6 from both sides - 8 = 2X divide both sides by 2 - 4 = X ------------------------check in original equation 2(-4) - 2 = 4(-4) + 6 - 8 - 2 = - 16 + 6 - 10 = - 10 checks
2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
2x -6 = 4 then 2x = 4 +6 x=10/2 = 5
4
2x - 6 = 4 2x = 4 + 6 = 10 x = 10/2 = 5 ∴ x = 5
2x-6
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
4 - 2x = 10 -2x = 10-4 -2x = 6 -x = 3 x = -3
2x > -6 and x - 4 < 3x + 3 > 2x + 1 and -4x < -8-6 < x + 3 < 6-3x > -6 or x - 5 < 2x - 2 > 2x + 1 or 10 > -2x + 2can someone please help me!

2x + 4 = y ...............2x + 4 = y ....................2x + 4 = y .............2*(-6)+ 4 = y x - y = 2 .......<=> ...x - 2x - 4 = 2 .....<=> ...x = -6......... <=>.... x = -6 ..............<=> y = - 8 x = - 6
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
2x+4 = -16 2x = -16-4 2x = -20 x = -10
