Question

determine which of following equations are linear in two in two variables 3x + 4=0, 4x-2y+5=0, 3х+ 4z=5, 3x^2+4x=1​

Answer 1

Answer:

2t−1=3t+5

A linear equation in one variable is an equation that can be written in the form ax+b=c, where a,b are real numbers. 

option (a) has two variables x and y.Hence it is a linear equation with two variables.

Option (b) has one variable t. Hence it is a linear equation with one variable

Option (c) and (d) is not a linear equation ∵ the highest power of x is 2.
