Y = 3x - 1 ---- (1)
x - y = -9  ---- (2)

From Equation 2:
x - y = - 9
x + 9 = y 
y = x + 9 --- (2a)

(1) - (2a):
0 = 3x - x - 1 - 9
0 = 2x - 10
2x - 10 = 0
2x = 10
x = 5 ---- sub into (1)

y = 3(5) - 1 
y = 15 - 1
y = 14

What is 3/4 as a percentage
luda_lava [24]

Answer:

75%

Step-by-step explanation:

A percent is a value out of 100.

Change the fraction \frac{3}{4} to an equivalent fraction with the denominator equal to 100.

\frac{3}{4} × \frac{25}{25} = \frac{75}{100}

This fraction represents a percent.

\frac{75}{100} = 75%
