is this system of equations consistent, inconsistent, or dependent

4x - 3y = 15

7y - 35 = (9 1/3) x

Did you try just graphing them at Desmos.com,? You can graph both lines on the same grid to see if they overlap, are parallel, or meet at a single point. You can also look up the terms above relative to systems of equations in your text or on the internet.

4x -3y = 15


7y -35 = (9 1/3)x = 28x/3


21y -105 = 28x


28x - 21y = -105


4(7x) - 3(7)y = 15(7)


one equation is a mutliple of the other,

graph them and they are the same line

there are an infinite number of solutions to the equations

they are linearly dependent

S/B 28x - 21y = 105. Think that changes your conclusion.
