X-4y=-11<=> -5x + 20y = 55
<span> 5x - 7y = -10</span>
=>0*x + 13*y = 45 => y =45/13 => x = 4*(45/13) -11 = 180/13 -11 =>
x = 37/13;

the answer is </span>3x-2x
Answer:
m ∠ L = 54°
Step-by-step explanation:
the angles of triangle are 2x, 3x & 5x
the sum of angles are 180°
2x+3x+5x = 180
10x = 180
x = 180/10 = 18°
m ∠ L = 3x° = 3(18)° = 54°
m ∠ L = 54°
