Answer: The value of y is 2
Step-by-step explanation:
If y=5-3 and 3x-y=-1
Take y=5-3 first
y = 5 - 3
y = 2
Then, take 3x-y=-1, and put y = 2 in the Expression
3x-y=-1
3x - (2) = -1
3x - 2 = -1
3x = -1 + (-2)
3x = -1 -2
3x = -3
To get x, divide both sides by 3
3x/3 = -3/3
x = -1
Thus, the value of y is 2 while x is -1
