Question

Find the solution to the system of equations: x + 3y = 7 and 2x + 4y = 8

1. Isolate x in the first equation:

2. Substitute the value for x into the second equation:

3. Solve for y:







4. Substitute y into either original equation:

5. Write the solution as an ordered pair:





x = 7 – 3y

2(7 – 3y) + 4y = 8

14 – 6y + 4y = 8

14 – 2y = 8

–2y = –6

y = 3

x + 3(3) = 7

Answer 1

x + y = 1

Step-by-step explanation:

X + 3y = 7

2x + 4y = 8

2x - x = x (1x)

4y - 3y = y (1y)

8 - 7 = 1

x + y = 1
