Step-by-step explanation:
by using substitution method
4x+2y=2-----i
2x+y=4-------ii
make y the subject of the formula in equation ii
2x+y=4
y=4-2x------iii
substitute equation iii into equation i
4x+2y=2
4x+2(4-2x)=2
4x+8-4x=2
collect like terms
4x-4x=2-8
0=-6
actually they're no solutions to this simultaneous equation
