First you solve for y.
5x+ y= 12 so Y= 12-5x
And plug it into the next equation
3x- 3(12-5x) = 18
Distribute
3x-36+15x=18
Add 36 to both sides
3x+ 15x= 54
18x= 54 ... divide
x= 3
And you can plug in x to solve for Y
5(3) + y = 12
15+ y = 12 ...subtract 15 from both sides
y= -3
The value of x is less than or equal to 2.25.
<h2>Linear system</h2>
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. It is a combination of infinite points side by side.
<h3>Simplification</h3>
Simplification is to make something easier to do or understand and to make something less complicated.
Given
The expression is 47.75 + x ≤ 50.
<h3>To find</h3>
The value of x.
<h3>How to find the value of x?</h3>
The expression is 47.75 + x ≤ 50.
On simplifying,
47.75 + x ≤ 50
x ≤ 50 - 47.75
x ≤ 2.25
Thus, the value of x is less than or equal to 2.25.
