Question

Compleate the solution of the equation. find the value of y when x =-2.

-9x-3y=6

Please help!!!

Answer 1

Y should equal 8. Plug in the variable X. So (-9) times (-2) equals 18. Now the equation is 18-3y=6. 18 plus 6 equals 24. 3y = 24. 24 divided by 3 is 8.

Answer 2

Substitute x for -2 so make it -9(-2)-3y=6. Multiply -9 and -2 to get positive 18, so 18-3y=6. What you do to one side, do to the other so subtract 18 from that side and the other. 0-3y=6-18. 6-18 is -12 and you can ignore the zero since it does nothing. -3y=-12. Divide both sides by 3 to get y=4.

Y is 4 when X is -2
