Answer:
x=30
Step-by-step explanation:
2x+x+90=180 (anglesome prop.)
3x+90=180
3x=180-90=90
3x=90
x=90/3=30
Use the point-slope formula: y-2 = 1(x-1), or y-2 = x-1, or y = x + 1 (answer)
5x + 4y = 8
-5x + 3y = -1
Let's add both equations, to eliminate x.
5x + 4y - 5x + 3y = 8 - 1
7y = 7
y = 1
Let us substitute this value of y in equation 1, so we can find x.
5x + 4 = 8
5x = 4
x = 4/5
