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
