Answer:
w = 2
Step-by-step explanation:
3 + 2w = 7
Subtract 3 from both sides.
2w = 4
Divide by 2.
w = 2
Check.
3 + 2(2) = 7
3 + 4 = 7
7 = 7
30/3= 10(if you do 30 divide by 3 then you need to divide 24 by 3 to)
24/3= 8
10x2= 20(same if you do 10 time 2 then you need to do 8 times 2)
8x2= 16
then add 30 and 24 with 20 and 16.
