4x+4y=12
(-4y) (-4y)
4x= 12-4y
Divide 4
12-4y/4= x
I really hope it makes sense

Hmm try 192.5 I think that’s right
In (-x)² you’re taking the value of x in the parentheses and then multiplying by the power of two while in just -x ² the power sign in directly on the number not on the parentheses. You will get the same answer both times for example x=10 (10)² or 10² both equal 100.
Week one:
36 * 6.70 = $241.20
Week two:
40 * 6.85 = $274
Subtract:
274 - 241.20 = $32.80
Therefore, he made $32.80 more the second week then he did the first week.
Best of Luck!
