<h3>How to Solve a System of Equations by Elimination?</h3>To solve a system of equations given using the elimination method, do the following:
Multiply 2x - 5y = 1 by 2 and multiply -3x + 2y = -18 by 5 to get the following:
4x - 10y = 2 --> eqn. 1
-15x + 10y = -90 --> eqn. 2
Add
-11x = -88
Divide both sides by -11
x = 8

Answer:
200 words are peter can be type in 5 minutes.
Step-by-step explanation:
As given
If peter can type 80 words in 2 minutes .
i.e
80 words = 2 minutes
Now words type in 1 minutes.
1 minutes = 40 words
Now calculate number of words are type in 5 minutes.
Words are type in 5 minutes = Number of minutes × Number of words are type in 1 minutes.
Number of minutes = 5 minutes
Number of words are type in 1 minutes = 40 words
Words are type in 5 minutes = 5 × 40
= 200 words
Therefore 200 words are peter can be type in 5 minutes.
