Question

Solve by elimination:
4x+4y=4
3x+4y=10

Answer 1

Answer:

x = 2

Step-by-step explanation:

By elimination method

3x + 4y = 10 .... (i)

4x - 4y = 4 ... (ii)

Multiplying equation (ii) and 1 by 2, we get 8x - 8y = 8 ... (iii)

6x + 8y = 20 ... (iv)

Adding equation (iv) and (iii), we get

14x + 0 = 28

x = 28/14 = 2

Answer 2

Answer:

x = 2

Step-by-step explanation:

By elimination method

3x + 4y = 10 .... (i)

4x – 4y = 4 ... (ii)

Multiplying equation (ii) and 1 by 2, we get

8x – 8y = 8 ... (iii)

6x + 8y = 20 ... (iv)

Adding equation (iv) and (iii), we get

14x + 0 = 28

x = 28/14 = 2
