Answer:
x=3, y=-6
Step-by-step explanation:
As you know there are many ways to solve this question! First is Subsitutuion, Second is Elimination, and Third is Graphing!
Let’s begin with our detailed answer:
As you know subsitution is solving for a variable and then it can be used as a variable substitution to figure out x and y.
So in our system of equations:
I will just take one equation and solve for x but it actually dosent matter which variable you subsitutue and solve for.
To eliminate this question we can divide the top part by -3:
Let‘s sum these system of equation and we get:
We can now insert y as -6 and solve for x:
So,
Answer:
x = 44°
Step-by-step explanation:
The sum of the three angles is 180°.
So, x + x + 5 + 2x -1 = 180
4x + 4 = 180
4x = 176
x = 44°
