Explanation:
4x+3y=37
y=x-4
4x+3(x-4)=37
4x+3x-12=37
add 12 to both sides
7x=49
x=7
Now you use plug in x
4(7)+3y=37
28+3y=37
subtract 28 to both sides
3y=9
y=3
answer: x=7 and y=3
We can use #11 as an ex.
7ab and 4 ab
So we combine 7 and 4 (multiply)
=28
Then combine "a". On both sides they are 2 a"s so it would be a^2 and same for b . b^2
Answer: 28a^2b^2.
