the sum of a number and 9 is multiplied by -2 and the answer is 8 find the number. I know the answer is -5 i need a expression, or equation. Any of them both HELP
Y+9x-2=8 That's the answer because y=-5 as yku said so to make an equation yiu could use that and you already solved it so it's Y plus 9 multiplied by -2 is equal to 8 :)
