Question

What is the value of the x variable in the solution to the following system of equations?
4x + 3y = 10
4x + 5y = 14
Answer
-2
2
1
-1

Answer 1

multiply second equation by -1 and then add the equations together
this will eliminate x but you can solve for y
and then use that y to plug into one equations given to find x

Answer 2

so its .... 1?

Answer 3

\[4x+3y=10\]
\[-(4x+5y=14)\]
---------------
0-2y=-4
-2y=-4
y=2
=>
4x+3(2)=10
4x+6=10
4x=10-6
4x=4
x=1

Answer 4

yes
