Answer:
isosceles triangle
Step-by-step explanation:
4x - 2y = 14
y = 1/2x - 1
4x - 2(1/2x - 1) = 14
4x - x +2 = 14
3x + 2 - 2 = 14 - 2
3x = 12
3x / 3 = 12/3
x = 4
2x = y -10
2x + 7 = 2y
y - 10 + 7 = 2y
y -y -10 + 7 = 2y - y
-3 = y
8x - 1/3 y = 0
12x + 3 = y
8x - 1/3y = 0
8x -1/3( 12x + 3) = 0
8x - 4x - 3 = 0
4x -3 + 3 = 0 + 3
4x / 4 = 3/4
x = 3/4
Multiply both sides by 4 to isolate the x term.
x = 5 × 4
x = 20
