solve using the addition method. what is the x-value of the solution to the system? 2x-3y=-1 3x+4y=24

AysviL [449]

Answer:

x-value is 4

Step-by-step explanation:

2x-3y=-1

3x+4y=24

We can solve the equation by eliminating y

We multiply the first equation by 4 and the second by 3

4(2x-3y=-1 )

3(3x+4y=24)

8x -12y = -4

9x +12y = 72

Then we add the two equations;

8x -12y = -4

9x +12y = 72

17x = 68

x = 4

Thus the x-value is 4

$\begin{gathered} x+3y=12 \\ 2x-4y=4 \end{gathered}$ $\begin{gathered} x=12-3y \\ \\ 2(12-3y)-4y=4 \\ 24-6y-4y=4 \\ 24-10y=4 \\ -10y=-20 \\ y=2 \\ \\ x=12-3(2) \\ x=12-6 \\ x=6 \end{gathered}$
