Question

Without graphing, group the systems based on the number of solutions. y=2x-3 y=-2x+3. So my question is how can I find if it has one solution no solution or infinity solutions

Answer 1

Step 1:

two system of linear equations has one solution

Step 2:

Let deduce the number of solution in the two linear equations

y = 3x - 3 ...............................equation 1

y = -2x + 3 ..............................equation 2

Step 3:

use substitution method to solve the system o
