Question

an orchard has 2030 trees. The number of trees in each row is 12 more than twice the number of rows. How many trees are in each row?

Answer 1

Let R = the number of rows
Let T = the number of trees per row

T = 12 + 2R
because of this:
The number of trees in each row is 12 more than twice the number of rows.

R*T = 2030

Answer 2

So, solve these two equations simultaneously by the substitution method:

T = 12 + 2R
R*T = 2030
-------------

R * ( 12 + 2R) = 2030

Solve for R.
