<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.
Given
He bought 2.5 pounds of apples that are x dollars a pound.
And 2 bags of lettuce for y dollars each.
The total cost is $2.
<h3>To find </h3>
The equation of this.
<h3>How to find the equation?</h3>
He bought 2.5 pounds of apples that are x dollars a pound.
Then the expression is 2.5x
And 2 bags of lettuce for y dollars each.
Then the expression is 2y
The total cost is $2.
Then the expression will be
2.5x + 2y = 2
2.5x + 2y - 2 = 0
Thus the equation is 2.5x + 2y - 2 = 0.

Answer:
113
Step-by-step explanation:
To find the result of the equation, you just have to apply the given information that x = 3 and y = -5 into the equation:
31x + y2 - (xy)2
= 31 * 3 + -5 * 2 - (3*-5) * 2
= 93 + -10 + 15 * 2
= 93 -10 + 30
= 83 + 30
= 113
