2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2x+2=x+5 x=3
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
4x + 2 = 2x + 5 Subtract through by 2x 2x + 2 = 5 Subtract through by 2 2x = 3 Divide through by 2 x = 1.5 ■
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
6x + 3 = 2x + 5 4x = 2 x=1/2
2x + 2 = 3x - 57 = x
X equals 2 :)
If x equals 2, then you first write out your equation 2x + 5 = y. You then fill out 2(2) + 5 = y. 2 x 2 = 4, so then 4 plus 5 equals 9.
That's not real clear. It could be 2 times positive 1 (which is 2) plus 5, which equals 7. It could be 2x + 1 + 5 which equals 2x + 6 It could be 2x + 1 = 5, in which case x = 2
X=27
