What is the solution to the system below

2x+y=3
4x+2y=9

a) (2,2)
b) (2,-2)
c) no solution
d) infinite solutions on the line

c)

multiply 1st eqn by 2 and u get : 4x + 2y = 6

using the 2nd eqn and the result above u have 6 = 9 which is non-sense

thanks for the correction Alejandroid Jerkbomb --- I usually correct my answers before moving on to the next question

2x+y=3
y=3-2x
4x+2(3-2x)=9
4x's cancel
2=9 ---it doesn't
c. No solution
Infinite solutions would exist if you got 2=2 or 9=9

@Paul you're wrong because 2(2x+y)=3(2)=6 which doesn't equal 9

2x + y = 3
y = 3 - 2x

4x + 2(3 - 2x) = 9
4x + 6 - 4x = 9
6 = 9

no solution
