simplify 5(x+1)−7(x−1)

9 - 2x

Step-by-step explanation:

5x + 1 - 7x + 8

9 - 2x

the simplified answer is 5x + 5 because when you distribute the 5 into the first parentheses you get 5x + 5 and when you distribute 7 into the second parentheses you get 7x - 7 so the equation would end up being 5x + 5

Step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
