A) 2x + 3y = 2. (1)
x - 2y = 8. (2)
modify (1) to be: 2x = 2-3y
= x = 1-1.5y
put (1) into (2) so: (1-1.5y)-2y = 8
-3.5 y = 7
3.5 y = -7
y = -7/3.5
y=-2

Answer:
y = -5x + 15
Step-by-step explanation:
10x + 2y = 30
Subtract 10x from both sides.
2y = -10x + 30
Divide both sides by 2.
y = -5x + 15
<span>The diagonals of the square are the same length and also perpendicular to each other, being perpendicular means that they meet at a 90 degree angle. The intersection where the two diagonals meet forms 4, 90 degree angles which creates a circle.</span>
