There are two formulae you can use to calculate the number of apple trees and the number of conifer

trees for the pattern described on the previous page:

Number of apple trees = n2

Number of conifer trees = 8n

where n is the number of rows of apple trees.

There is a value of n for which the number of apple trees equals the number of conifer trees. Find the

value of n and show your method of calculating this.

Find four different solutions of the equation 4x+ 5y= 20.The given linear equation in two variables is 4

x+ 5y= 20.We can obtain the solution of the equation by substituting the value of one variable and obtaining the value of the other variable.

If we take

x= 0, we obtain4 × 0 + 5

y= 20,5

y= 20or

y= 4Therefore, (0, 4) is a solution of the given equation.

Now, taking

y= 0, we obtain4

x+ 5 × 0 = 204

x= 20x= 5Therefore, (5, 0) is a solution of the given equation.
