Please helpp it would mean a lottt:)

(-8,-2)

Step-by-step explanation:

x=2y-4 (equation 1)

7x+5y=-66 (equation2)

Substitute equation 1 in 2

7(2y-4)+5y=-66

14y-28+5y=-66

19y= -66+28

19y= -38

y= -38/19

—>y=-2

Now substitute y=-2 in equation 1

x=2y-4

x=2(-2)-4

x=-4-4

—> x=-8

==>(-8,-2)

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
