now i have to solve for y. i already no that x=-1.
y=-1-2
y=3(-1)+2
-1 -2 = -3
3(-1)+2 = -3 +2 = -1
THANX I WAS SO CONFUSED ON THAT
To solve for y when x = -1, you need to substitute that value of x into the equation and evaluate the expression. Let's go through the steps:
1. Start with the equation: y = -1 - 2.
2. Substitute x = -1 into the equation: y = -1 - 2.
3. Evaluate the expression: y = -3.
So, when x = -1, the value of y is -3.
Now, let's solve the second equation:
1. Start with the equation: y = 3(-1) + 2.
2. Substitute x = -1 into the equation: y = 3(-1) + 2.
3. Simplify the expression: y = -3 + 2.
4. Continue simplifying: y = -1.
So, when x = -1, the value of y in the second equation is -1.
The solutions for y are -3 and -1, respectively, for the two equations.
I hope this explanation helps clarify the process for you! Let me know if you have any further questions.
