What is the value of x in the solution to the system of linear equations? {y=3x+2 y=x-4 a –7 b –3 c 1 d 5

b. -3

Step-by-step explanation:

the system is:

to find the value of x, we need to eliminate the y variable.

We can eliminate the 'y'  by substracting the equations:

which is simplified to:

and clearing for x:

which is option b.
