Step-by-step explanation:
x + y = 6
relationship: x = 6 -y or y = 6-x
so answer: c. y = 6 - x

simplify
y = 6-x

Answer: a=-3.4
Step-by-step explanation: you mean solve for a:)
-2a+7-3(-9-4a)=0 We would have to equal this equation to 0
-2a+7+27+12a=0 We multiply the -3 with the parentheses
10a+34=0 Add the like terms, and subtract 34 from both sides
10a=-34 Then divide both sides by 10
a=-3.4
