Please help with these, will give brailiest if correct

Answer 1

Answer:

Well, Let's solve the problem of 3ₓ + 2y = 7.

We got to add -2y of both sides: 3ₓ + 2y + -2y = 7 + -2y

3ₓ = -2y + 7

Then after that we got to divide both sides of 3: $\frac{3x}{3}$ = $\frac{-2y + 7}{3}{$

ₓ = $\frac{-2}{3} y$ + $\frac{7}{3}$

Which your answer will be is ₓ - $\frac{-2}{3} y$ + $\frac{7}{3}$. Well,  Let's solve ₓ - 2y = 5. You got to add -x of both sides: ₓ - 2y + -x = 5 + - x  -2y = -x + 5. Then you do the same thing divide them both sides: $\frac{-2}{-2}$ = $\frac{-x + 5}{-2}$, Than: y = $\frac{1}{2} x$ + $\frac{-5}{2}$. So, Basically your answer will be is y = $\frac{1}{2} x$ + $\frac{-5}{2}$. Good Luck!

Answer 2

Answer:

y = -1

x = 3

Step-by-step explanation:

First, change one of the equation into y = mx + b form.

3x + 2y - (2y) = 7 - (2y)

3x/(3) = (7 - 2y)/(3)

x = 7/3 - 2/3y

Now, plug this equation into the x of the other equation.

(7/3 - 2/3y) - 2y = 5

7/3 - (7/3) - 8/3y = 5 - (7/3)

(-8/3y)/(-8/3) = (8/3)/(-8/3)

y = -1

To find x, substitute -1 for y in either equation and solve.

x - 2(-1) = 5

x + 2 - (2) = 5 - (2)

x = 3
