Let us say that:
x = hours worked by Wolfgang
y = hours worked by Heinrich
So that:
x = y + 10
14 x + 12 y = 3520
By combining the two equations:
14 (y + 10) + 12 y = 3520
14 y + 140 + 12 y = 3520
26 y = 3380
y = 130 hours
x = y + 10 = 140 hours
<span>So Wolfgang worked 140 hours while Heinrich worked 130
hours.</span>
Because if you put a two on one side and put the inverted version of 2, then join them on their lines, it forms a fish. I have more of those types of questions:
1+1=田
2+2=fish
3+3=8
4+4=↑
5+5=cylinder
6+6=headset
7+7=▼
8+8=butterfly
9+9=cup
<span>0+0=0</span>
Its a simultaneous equation:
lets make "x" the used games and "y" the new ones
4x + 2y = 84
6x + y = 78. (multiply this by 2 to cancel out y)
12x + 2y = 156
so now we subtract them:
12x - 4x = 156 - 84
x = 9
used games cost $9
new games cost 78 - 6(9) = $24
Janet has $120 but she already bought 3 NEW games so:
120 - 3(24) = $48 left
48/9 = how many used ones she can buy = 5. something
she can buy 5 used
