Answer:

I will go for a part the rest You can do by yourself

Step-by-step explanation:

Multiply the second equation to get same amount of x in both equations

2x=2-3y/2

multiply both equations by 2 to get rid of the fraction in second equation

4x+14y=34

4x=4-3y

subtract equation(2) from equation(1)

14y=30+3y

11y=30

y=30/11, x=-23/22

2x+34=6-5x pls help show work I’ll mark as brainliest!!

Answer:

x = -4

Step-by-step explanation:

2x + 34 = 6 - 5x

Subtract 34 from both sides.

2x = -28 - 5x

Add 5x to both sides.

7x = -28

Divide both sides by 7.

x = -4

Proof:

2x + 34 = 6 - 5x

Substitute variable.

2(-4) + 34 = 6 - 5(-4)

Multiply.

-8 + 34 = 6 + 20

Add.

26 = 26
