you want answer or solution?

Answer 2

Solution please

Answer 3

Substitute your second equation in first..i mean like this...
2x + 8y = 3
2(8-4y) + 8y = 3
16 - 8y = +8y = 3
16 = 3
what???
okay, the lines are parallel. there is no solution..

Answer 4

the third line of solving is
16 - 8y +8y = 3

Answer 5

umm..did you understand?

Answer 6

so y=13?

Answer 7
