Question

Solve the following system of equations using substitution: x = 2y +6 and 2x + y = -8​

Answer 1

Answer:

x= -2 , y = -4

Step-by-step explanation:

x =2y+6___(I)

2x+y=-8___(ii)

puting value of x in 2nd equation

2(2y+6) +y = -8

4y +y +12 = -8

5y = -8+(-12)

5y = -20

y = -4

x = 2(-4)+6

x = -2
