Mathematics

Answer:

y = -2    x = 0

Step-by-step explanation:

1. 3x-4y = 8

2. 18-5y = 10

Multiply equation 1 by 6

3. 18x-24y = 48

Subtract equation 2 from equation 3

4. -19y = 38

        y = 38/-19

        y = -2

Sub y = -2 back into equation 1

      3x-4(-2) = 8

      3x + 8 = 8

      3x = 0

      x = 0/3

      x = 0

It will be 25cm long Since it growing 10cm every 2 years it must be growing 5cm every year 10/2=5/1 To find total growth in 5 years multiply the cm it grows every year by the number of years so 5yearsX 5cm =25cm
