Answer:
y= -11
Step-by-step explanation:
After rearranging equation 2, we get x= y+3/2
Sub it into equation 1
y= 3(y+3/2) + 1
y= 3y+9/2 + 1
y= 3y + 11 / 2
2y = 3y + 11
-y = 11
y = -11
Im not sure how to do it because you don't have a plus or minus sign. add that and then i will show you.
Answer: x = 9, y = -14
Explanation:
4x + y = 16
2x + y = -2<span>
</span> 4x + y = 16
- 2x + y = -2
-------------------
2x + 0 = 18
-------------------
2x = 18
x = 9 <<<<< ¯\_(ツ)_/¯ For the value of x
Plug x = 9 into 2x + y = -2
2(9) + y = -2
12 + y = -2
y = -14 <<<<< ¯\_(ツ)_/¯ For the value of y
