Answer: x=2

Explanation:

Substitute y=3x−5 into 6x+3y=15.

15x−15=15

2. Solve for x in 15x−15=15.

5x−15=15

Add 15 to both sides.

15x=15+15

Simplify 15+15 to 30.

15x=30

Divide both sides by 15.

x=30/15

Simplify 30/15 to 2.

x=2

6x + 3(3x - 5) = 15

6x + 9x - 15 = 15

15x = 15 + 15

15x = 30

x = 30/15

x = 2

y = 3(2) -5

y = 6-5

y = 1

Solution: (2,1) and x = 2

//Hope this helps.
