Answer:
x=1, y=3
Step-by-step explanation:
Rearrange equations 1 and 2 so that y is the subject
3x^2 = xy
Equation 1) y = 3x
Equation 2) 2y = 5x + 1
multiply the first equation by 2
2y = 6x
2y = 5x + 1
subtract the 2 equations from each other
2y - 2y = 6x - (5y +1)
0 = x - 1
x = 1
substitute x = 1 in the second equation
2y - 5(1) = 1
2y = 1 + 5
2y = 6
y = 3
