Hey there!
Let's solve these equations.
The first one is
3x=15
Divide both sides by 3:
x=5 (Answer)
x+4=7
x=7-4
x=3 (Answer)
4y+3=11
4y=11-3
4y=8
y=2 (Answer)
2x+1=13
2x=13-1
2x=12
x=6 (Answer)
x/2-4=1
x/2=5
x=10 (Answer)
x+3=8
x=8-3
x=5 (Answer)
2y-5=1
2y=1+5
2y=6
y=3 (Answer)
_______________________
5x=40
x=8 (Answer)
_________________________
y/3+1=7
y/3=7-1
y/3=6
y=18 (Answer)
Hope everything is clear.
