Answer:

6[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

In this equation I will do the elimination method.

3x-y=6

3x+y=34

6x=40

Simplify

x=6[tex]\frac{2}{3}[/tex].

Check:

3(6.666...)-y=6

20-y=6

-20 from 6

-y=-14

y=14

20-14=6

6=6

3x(6.666...)+y=34

20+14=34

34=34

To begin, we can convert the equations into slope-intercept form:

3x - y = 6 → y = 3x - 6

3x + y = 34 → y = -3x + 34

Next, we plug it in to become an equation with variables on both sides:

3x - 6 = -3x + 34

→ 6x - 6 = 34

→ 6x = 40

→ x = 6 2/3 OR 6.66666
