Question

A system of equations is shown below:

Answer 1

Answer:

The x-coordinate of the solution to this system of equations is $2$

Step-by-step explanation:

we have

$3x-y=2$ ------> equation A

$x+y=6$ ------> equation B

Adds equation A and equation B

$3x-y=2\\x+y=6\\--------\\ 3x+x=2+6\\4x=8\\x=2$

Answer 2

3x − y = 2

y = 3x - 2

x + y = 6

x + 3x - 2 = 6

4x - 2 = 6

4x = 6 + 2

4x = 8

x = $\frac{8}{4}$

x = 2

Hence, the x co-ordinate is 2.
