1a = 80%
1b = 125%
please give thanks/brainlist if correct
The correct answer is B
When you put the values of x and y in the equation
3(3) - 4(-1) = 13
9 + 4 =13
13=13 (correct answer)
When you try putting the rest of the values in the equation the answer doesn’t match ,hence ,the correct answer is B.I hope I get the brainliest answer!
So I will choose to cancel the y first because that is easiest. To do this, add both equations together.
x+y = -3
+
x - y = 13
This will give us:
2x = 10
therefore, x = 5
Now, we can plug this into the first equation to find y
5+y = -3
y = -3 - 5
y = -8
Answer:
x = 5
y = -8
Hope this helped!! :D
