Answer:Hm
Step-by-step explanation:
Distribute 7 to 3x and -2, and 4 to x and 5
7(3x - 2) = 21x - 14
4(x + 5) = 4x + 20
Combine like terms
21x + 4x = 25x
-14 + 20 = 6
25x + 6 is your answer
hope this helps

x+y=5
x-y=4
---------
x+y=5
x=4+y
--------
(4+y)+y=5
4+y+y=5
4+2y=5
2y=1
y=0.5
x=4.5
---------
x²-y²=(4.5)²-(0.5)²=20.25-0.25=20
