1. 3x-10=x+70
+10 -x
2x=80
x=40
2. x+27+2x-39=180
3x-12=180
+12
3x = 180
x = 64
3. 2x ÷ 80=5x+44
- 2x -44
36= 3x
12=x
Here, x - y = 2342
x = 2342 + y
Substitute this value into first equation,
2342 + y + y = 3500
2y = 3500 - 2342
y = 1158/2
y = 579
So, x = 2342 + 579 = 2921
In short, Your Answer would be 2921 contemporary titles
Hope this helps!
