Answer:
4 = 6
5 = -17
Step-by-step explanation:
4. a² - b / b² - c
a² = 2² = 4
b = -2
4 - (-2) = 4 + 2 = 6
6 / b² - c = 6/4 - 3 = 6/1 = 6
4 = 6
5. -3x² + 2xy + 7
-3x² = -3 * -2² = -3 * 4 = -12
2xy = 2 * -2 * 3 = -4 * 3 = -12
-12 + -12 + 7 = -24 + 7 = -17
5 = -17

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
