Question

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

Answer 1

x-value is 4

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
