Cancel 5x: -2(x-2)=-7-7.
expand: -(2x-4)=-7-1.
simplify: -2x+4=-8
substitute number: -2(6) + 4=-8
answer: 6

Answer:
You can buy 7 additional donuts
Step-by-step explanation:
$0.50 times 7 is $3.50 and $7.50 plus $3.50 is $11 dollars so you would be able to get 7 additional donuts
You are asked to find the missing value in
... 40 + ? = 70
given that it is also the solution to
... ? + 5 = 35
Either way, you subtract the constant that is on the same side of the equation as the unknown.
... 40 + ? - 40 = 70 - 40
... ? = 30 . . . . the missing value
_____
You can check to see if this also satisfies the equation
... 30 + 5 = 35 . . . . . . . true
