Answer:
Y is 2
Explanation:
First, Solve the equation for the variable y
2y = -3x + 31 : y = -3x/2 + 31/2
Plug this in for variable y in the equation:
2x - 5•(-3x/2+31/2) = 8
19x/2 = 171/2
19x = 171
Solve first equation for the variable x
19x = 171
x = 9
now knowing that x=9, you can plug it into either equation to solve for y.
y = -(3/2)(9)+31/2 = 2
