It is B because u need enough for it to do it right
<span>2x + 4y = 36
3x - 4y = -6
--------------add
5x = 30
x = 6
</span>2x+4y=36
2(6)+4y=36
12 + 4y = 36
4y = 24
y = 6
answer
<span>(6, 6) is a solution of equations
</span><span>(4,7) is NOT a solution of equations</span>
1) you add the variables in the bracket
(4+5)÷3×4
9÷3×4
2) you multiply 3 by 4
9÷3×4
9÷12
3) now you divide 9 by 12
9÷12
=0.75
