The answer is A
You can solve this by equation the two equations, by substitution method or elimination. Let's choose the substitution since Equation 2 has already X isolated
-take the X in equation 2 and substitute in the first equation
So, You should have 5 (5-3/2 y) -4y =7
Get y ( I'll assume you know how to simplify and find y by yourself )
y=36/23
-Now take y and substitute it in the first equation or the second equation (it doesn't really matter)
Substituting y in Equation 2:
x=5- 3/2 (36/23)
=> x= 61/23
So answer is A where (x,y) is (61/23, 36/23)

You then would eliminate 6, by adding 6 to both sides

Then you want all of the X's on the same side, so you subtract 2x from both sides.

Then to isolate the X, you divide by 2

The answer is x=2
Answer:
the answerrrr is uuuuuuuuuuuuuuuhhhhhhhhhh hmmm
Step-by-step explanation:
Multiply 3&8 and 3&7, this expands it to 24 + 21.
