2x – 5y = 1
3x – 4y = -2

Step-by-step explanation:

2x - 5y = 1   (times 3) 6x - 15y = 3

3x - 4y = -2 (times 2) 6x - 8y = -4

.

6x - 15y = 3

6x - 8y = -4    

-7y = 7

y = -1

.

Substitute the value of y to one of equations

2x - 5y = 1

2x - 5(-1) = 1

2x + 5 = 1

2x = 1 - 5

2x = -4

x = -2

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
