Answer:
i believe its the second part thats wrong
Step-by-step explanation:
1 Distribute
−5(−2+10)=20
10−50=20
2 Add 50 to both sides of the equation
10−50=20
10−50+50=20+50
3 Simplify
Add the numbers
10x−50+50=20+50
10=20+50
Add the numbers
10x =20 + 50
10x=10
4 Divide both sides of the equation by the same term
10x = 70
10x 70
---- = ----
10 10
5 Simplify
Cancel terms that are in both the numerator and denominator
10x 70
---- = ----
10 10
70
x = ----
10
70
x = ----
10
x=7
Solution
= 7
hopes it helps and list brain list plz
Answer: 7 times 4
Step-by-step explanation:
last one is the right answer
You would plug in the y=9 into the first equation and then have the expression 9=9x-9
. After going through the first steps of solving an expression you would get 18=9x. X=2. Then you would plug in the x value into the first expression to get y=9.
