Answer:
the answer is (6,6)
Step-by-step explanation:
subtract 1 from 7.( 6,6)
you would cross multiply meaning 6(2x+2)=11(x-4) Then you distribute 6 so it would be 12x+12=11x-44 then you have to move the constant and the variable so 12x-11x= -44-12 so then the answer would be x = -56
<u>21</u> is 75% of 28
75% = 0.75
28(0.75) = 21
