Answer:

  • (0, 2)

Explanation:


\tt y=x+2\\3x+3y=6

Substitute y= y=x+2 into 3x+3y=6


  • \tt 3x+3(x+2)=6

  • \tt 6x+6=6

Solve for x :-


  • \tt 6x+6=6

Cancel 6 from both sides:-


  • \tt 6x=0

Divide both sides by 6:-


  • \tt \cfrac{6x}{6} =\cfrac{0}{6}

  • \boxed{\bf x=0}

Now, Let's solve for y:-

Substitute x = 0 into y=x+2


  • \tt y=0+2

  • \boxed{\bf y=2}

Therefore, x = 0 and y = 2.

_________________

Check:-

To check a system of equations by substitution, we plug the values for x and y into the equations, If both simplified are true then your answer is correct.

Equation 1 :-

y = x + 2

  • (2) = 0 + (2)
  • 2=2

Equation 2 :-

3x+3y=6

  • 3(0)+3(2)=6
  • 0+6=6
  • 6=6
