What is the solution for this system x+y=6 2x+4y=20

Sagot :

Answer:

It is a linear equation

solving by substitution method

x + y =6 ------ eqn 1

2x + 4y =20 -------- eqn 2

x = 6 - y ------ eqn 3

putting the value of x from eqn 3. into eqn 2.

2(6-y) +4y =20

12 - 2y + 4y =20

12 +2y =20

2y = 20-12

2y = 8

2y / 2 =8/2

y =4

put the value of y into eqn 3

x =6 - y

x = 6 - 4

x = 2

Therefore x = 2, y= 4
