Answer:

(x,y)=(2,-6)

Explanation:

we are given system of equations as


x=(1)/(2)y+5


2x+3y=−14

now, we can plug first equation into second equation


2((1)/(2)y+5)+3y=−14

now, we can solve for y


2\cdot (1)/(2)y+2\cdot \:5+3y=-14


4y+10=-14

Subtract both sides by 10


4y=-24

divide both sides by 4


y=-6

now, we can plug back y=-6 and find x


x=(1)/(2)*-6+5


x=-3+5


x=2

so, we get solution as

(x,y)=(2,-6)
