Step-by-step explanation:

$f(x) = 7x - 6$

$\:$

Inverse

$y = 7x - 6$

$x = 7y - 6$

$x + 6 = 7y$

$y = \frac{x + 6}{7}$

${f}^{ - 1} (x) = \frac{x + 6}{7}$

 \left \{ {{10x+2y=300\ \ \ \ \ \ \ \ \ \ \ \ } \atop {8x+4y=360\ \ \ | divide\ by\ -2}} \right. \\\\
 \left \{ {{10x+2y=300} \atop {-4x-2y=-180}} \right. \\\\+----\\addition\\\\\
6x=120\ \ \ | divide\ by\ 6\\\\
x=20\\\\
y=\frac{300-10x}{2}=150-5x=150-5*20=150-100=50\\\\

Answer:

Therefore the value of 'y' is,

$y=3$

Step-by-step explanation:

Given:

$10y-50=-20$

To Find:

y= ?

Solution:

$10y-50=-20$ ........Given

Step 1. Adding 50 to both the side we get

$10y-50+50=-20+50\\10y=30$

Step 2. Dividing by 10 on both the side we get

$\dfrac{10y}{10}=\dfrac{30}{10}\\\\y=3$

Therefore the value of 'y' is,

$y=3$
