Find the inverse of the following relation:{(-2,5), (0,4), (3,-8), (7,5)}

Did you put in a negative answer? no matter if you + - ÷ or ×, it will be negative example: -21 ÷ 3 = -7

1) add 6 to 24, write the rest of the equation 10-2x= 30 subtract 10 from 30 2x=20 divide 20 by 2 and x=102) add 3 to -9 write the rest of the equation 4x+3=-6 subtract 3 from -6 4x=-9 x= -2.25  i don't know the rest sorry
