Question

What is the value of x in the solution to the system of equations?3x + 2y = 125x – 2y = 4

Answer 1

x = 2

Step-by-step explanation

We want to find the value of x that is a solution to the system of equations:

`\begin{gathered} 3x+2y=12 \\ 5x-2y=4 \end{gathered}`

We can solve this by elimination.

To do this, add the two equations:

`\begin{gathered} 3x+2y+(5x-2y)=12+4 \\ 3x+5x+2x-2x=16 \\ 8x=16 \\ x=(16)/(8) \\ x=2 \end{gathered}`

That is the value of x that is a solution to the system of equations.
