Question

Simplify the following if x = 3 & y = 4:

1. 2x + y =

2. 3x + 2y =

3. 3y + 2x =

4. 10x + 4y + 2x =

5. 6y + 5x =

6. 7x + 4y =

Answer 1

Just enter the information in x and y. For example,

As we know, x = 3 , y = 4

So....

1. 2 (3) + 4

6 + 4 = 10

2. 3 (3) + 2 (4)

9 + 8 = 17

Try to do the rest questions by yourself. It's easy! All the best.
