Question

if you are asked to solve a system of equations in which there is no linear equation to start with, you can sometimes begin by isolating and substituting a variable that is squared in both equations.

a. true

b. false

Explanation:

When solving a system of equations with no linear equation initially, if a variable is squared in both equations, we can isolate that squared variable from one equation and substitute it into the other. For example, in a system with \(x^2\) in both, isolate \(x^2\) from one and plug into the other to solve. So the statement is true.

Answer:

A. True
