Answer:
x = 10
y = 0
Step-by-step explanation:
1/2 x - 1/3 y = 5 ......1
x = 2/3 y + 10 ......2
substituting equation 2 in 1
1/2( 2/3y + 10) - 1/3y = 5
0.5(0.6667y + 10) - 0.3333y =5
0.33335y + 5 - 0.3333y = 5
0.33335y - 0.3333y = 5 - 5
0.00005y = 0
y = 0
substitute y = 0 in equation 2
x = 2/3(0) + 10
x = 0 + 10
x = 10
