24 es la b espero que te sirva
Answer:
Step-by-step explanation:
4x+y=14
x-2y=8
then;
x=8-2y
substitute;
4(8-2y)+8-2y=14
32-8y+8-2y=14
40-10y=14
26=10y
y=2.6 , work out 4x+2.6=14 to get x

Answer:
Detail in steps
Step-by-step explanation:
∠ABY + ∠YBC = 180
(x + 25) + (2x + 50) = 180
3x + 75 = 180
3x = 105
x = 35
m∠YBC = 2 x 35 + 50 = 120
m∠BEF = 5 x 35 - 55 = 120
m∠YBC ≅ m∠BEF
∴ AC // DF
