x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
3X+2=2X-5 -2 -2 __________ 3X= 2X-7 -2X -2X __________ X=-7 Check: 3(-7)+2=2(-7)-5 -19=-19 :)
4x + 5 = 2x + 19Subtract 5 from each side:4x = 2x + 14Subtract 2x from each side:2x = 14Divide each side by 2:x = 7
4-2x-9 = -19 -2x = -19-4+9 -2x = -14 x = 7
6x - 5 = 19 + 2xAdd 5 to each side:6x = 24 + 2xSubtract 2x from each side:4x = 24Divide each side by 4:x = 6
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7

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.
4x + 5 = 2x + 19Subtract 5 from each side:4x = 2x + 14Subtract 2x from each side:2x = 14Divide each side by 2:x = 7
4-2x-9 = -19 -2x = -19-4+9 -2x = -14 x = 7
7
6x - 5 = 19 + 2xAdd 5 to each side:6x = 24 + 2xSubtract 2x from each side:4x = 24Divide each side by 4:x = 6
Not calculus. x + 2x + 5 = x + 19 3x + 5 = x + 19 Combine like terms 2x + 5 = 19 Subtract x from both sides 2x = 14 Subtract 5 from both sides x = 7 Divide both sides by 2.
2x = 5 x = 2.5
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
answer is 4 7x+19=-2x+55 +2x +2x 9x+19= 0 55 -19 -19 9x = 36 9 9 =4
If your question was 2X + 5 =10. X equals what? Then X=2.5
