Add the three angles and set them to 180
4x-13+15+x+18=180
5x+20=180
5x=160
x=32
Then plug in to get A and C
A=4*32-13
A=115
C=32+18
C=50
I believe the answer is 2783 for 1 a - either

Here is your answer if thats is what you where asking for
Step-by-step explanation:
I really hope this helps! Look at the image I Uploaded.
(-1, 0)
Start by adding -2x to both sides of the second equation. Then substitute that equation into the first.
3x+3(2x+2)=-3
Solve the equation for x.
When you've found the value of x, substitute that value into the equation with the isolated y.
y=2(-1)+2
