X+(x+1)+(x+2)+(x+3)=156
4x+6=156
4x=150
x=37.5 (not an integer)
If x=37 you get 37+38+39+40=154 and if x=38 you get 38+39+40+41=158[/tex]

Step-by-step explanation:
2x+3y=23 2x+3.7=23 2×1 + 3×7 = 23
3y= 23 2×+21= 23 2 + 21 = 23
23÷3 = 7 2x= 23-21
y=7 2x= 2
x= 1
5x+3y=17 5×4+3y=17
5x=17+3 20+3y=17
5×=20 20=17+3y
14÷5 = 4 20=20+y
x=4 y=20-20
y=0
