Part a: the equation 2x - 4y = 12 is it 1 or 2
1) can be used to write an equivalent system
2) can't be used to write an equivalent system

part b: the equation 22x + 7y = 33
1) can be used to write an equivalent system
2) can't be used to write an equivalent system

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
