Question

Solve the system:

Answer 1

Answer:

$y=2,\ z=\frac{3}{5}$

Step-by-step explanation:

Given the following system of equations:

$\left \{ {{22-4y= 14} \atop {3y + 5z =9}} \right.$

You can follow these steps to solve it using the Substitutiong method:

1. Solve for "y" from the first equation in order to finds its value:

$22-4y= 14\\\\-4y= 14-22\\\\y=\frac{-8}{-4}\\\\y=2$

2. Substitute the value for "y" into the second equation and solve for "z" in order to find its value. This is:

$3(2) + 5z =9\\\\5z=9-6\\\\z=\frac{3}{5}$
