1. 1. Which of the following are linear equations in two variables? If not, state the reason. 4x + 3y - 2x - 5 4. 28y + 4 = 3y + 2 = 1 3y X-3 3x = 6xy - 4 5. + 5x = (y + 4) 8. 2x- - 3x + 2=0 3 1 3. 5(x + 3) = 10y - 2x 6. Зу 2 2 - 4x

Answer:
Linear equations in two variables are the algebraic equations which are of the form y = mx + b, where m is the slope and b is the y-intercept. They are the equations of the first order. For example, y = 2x+3 and 2y = 4x + 9 are two-variable linear equations.
