Question

Determine the number of solutions for this system of equations by inspection only. Explain.

4x + 7y = 17
20x +35y = 118

Answer 1

Explanation:

First of all

4x+7y=17

you group like terms

so all variables will go to one side

so dey are all grouped already so

you add the number attached to de variables which is 11xy=17

2.55xy=118
