if 3x+5=x+19 then x=7
3x+7=19 3x=12 minus 7 from both sides x=4 divide by three on both sides leaving just what x equals

It is (-1, 3).
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4

An equation where x equals 3.
x equals 19
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
if 3x+5=x+19 then x=7
7
19 plus 54 equals 73. when you subtract like this x+19=73 X+19=73 -19 -73 0 54
If your expression is 5x + 4 = ? and x = 3, then the answer is 19. If the expression is 5(x + 4) = ? and x = 3, then the answer is 35.
x=4 y=0

(4 + 2x) - (-2x + 1) = 13 + 6 4 + 2x + 2x -1 = 19 4x +3 = 19 4x = 19 - 3 4x = 16 therefore x = 16/4 x = 4
X=2
