Question

4x + 2y = 2
2x + y = 4

Step by step explanation please

Answer 1

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

Answer 2

No solutions

Explanation:

4x + 2y = 2

2x + y = 4

we need to evaluate for y is "2x + y = 4" to be able to solve this.

2x + y = 4

2x - 2x + y = 4 - 2x

y = -2x + 4

4x + 2y = 2

4x + 2(-2x + 4) = 2

4x -4x + 8 = 2

8 = 2

NO solutions
