I need to solve this system of equations, how do I do that?
3x-4y=20
y=3/4x-5

Is is Infinitely many solutions so 0=0

Step-by-step explanation:

Equation 1: 4y - 3x = -20

Equation (2):  y - 3x/4  = -5

Multiply equation (2) by 4

Equation 1: 4y - 3x = -20

Equation (2): 4y - 3x = -20

y = 3x/4 - 5

4•(3x/4-5) - 3x = -20

Therefore the answer leads to:

Infinitely many solutions, 0=0

Hope this helped :')

step-by-step explanation:

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
