The given equation is

To solve for x, we have to subtract 8 to both sides

Now we need to get rid of -9 from the left side, and for that we do division


Answer:I think its D
Step-by-step explanation:
You need to d to one side of the equation by itself and them use PEMDAS to solve your answer
Answer:
just type the values in your google
Step-by-step explanation:
Answer:
x=2
y=3
Step-by-step explanation:
y=−2x+7
y=5x−7
Set the two equations equal since they are both equal to y
−2x+7
=5x−7
Add 2x to each side
-2x+7+2x = 5x-7+2x
7 = 7x-7
Add 7 to each side
7+7 = 7x-7+7
14 =7x
Divide by 7
14/7 = 7x/7
2 =x
Now find 7
y = 5x-7
y = 5(2) -7
y = 10-7
y = 3
