Question

Find a solution to the following system of equations.

2x + 4y = 8
x + 4y = 6

Answer 1

best way is to eliminate y.

Answer 2

x = 2, y = 1

Answer 3

x= 2
y= 1

Answer 4

x + 4y = 6
=> x=6-4y
substituting x in the first equation
2(6-4y)+4y=8
12-8y+4y=8
12-8=8y-4y
4=4y
=> y=1 -->(1)
substituting (1) in equation 1
x+4(1) =6
x=6-4
x=2
therefore x=2,y=1
