Isolate x in the first equation:
2. Substitute the value for x into the second equation:
3. Solve for y:
x = 7 – 3y

2(7 – 3y) + 4y = 8

14 – 6y + 4y = 8

14 – 2y = 8

–2y = –6

y = 3

x + 3(3) = 7
4. Substitute y into either original equation:
5. Write the solution as an ordered pair

If y is substitute into either of the original equation. The  solution as an ordered pair are: x=-2; y=3.

The solution as an ordered pair

x + 3y= 7 equation 1

x+2y=4 equation 2

Solving for y

x+3y-(x+2y)=7-4

x+3y-z-2y=7-4

3y-2y=7-4

y=7-4

y=3

Substitute y=3 into equation 2

x+2y=4

x+2×3=4

x+6=4

Collect like terms

x=4-6

x=-2

Therefore the  solution as an ordered pair are: x=-2; y=3.
