I guess it decreases by 4 everytime so -4??? If thats what your asking
Step-by-step explanation:
30,26,22,18,14,10,8,4,-2.
Using the substitution method to solve the linear system the value of x and y is 1 and 2 respectively.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width.
Given
The equations are shown below.
y = 5 - 3x .....1
5x - 4y = -3 .....2
Substitute equation 1 in equation 2. Then
![\begin{aligned} 5x - 4(5-3x) &= -3\\\\5x - 20 + 12x &= -3\\\\17x &= -3 +20 \\\\17x &= 17\\\\x &= 1\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%205x%20-%204%285-3x%29%20%26%3D%20-3%5C%5C%5C%5C5x%20-%2020%20%2B%2012x%20%26%3D%20-3%5C%5C%5C%5C17x%20%26%3D%20-3%20%2B20%20%5C%5C%5C%5C17x%20%20%26%3D%2017%5C%5C%5C%5Cx%20%26%3D%201%5Cend%7Baligned%7D)
Then substitute the value of x in equation 1.
![y = 5- 3x\\\\y = 5-3*1\\\\y = 2](https://tex.z-dn.net/?f=y%20%3D%205-%203x%5C%5C%5C%5Cy%20%3D%205-3%2A1%5C%5C%5C%5Cy%20%3D%202)
Thus, the value of x and y is 1 and 2 respectively.
