How do you solve a system of equations by multiplying

Mathematics
1 answer:
juin [17]3 years ago
7 0

Answer:

A solution to a linear equation is a pairing of an x and y value that makes the equation true. The solution is given as a coordinate pair, such as (3,4). The equation y=4x-6 has an infinite number of solutions.

A few of the solutions to y=4x-6 are (4,10),(0-6), and (-2,-14); (10)=4(4)-6, (-6)=4(0)-6, and (-14)=4(-2)-6.

A system of linear equations are two or more linear equations that have been grouped to be solved together.

These two equations could be considered a system:

y=5x-8

2x+5y=30

A solution to a system of linear equations is a coordinate pair (x,y) that makes all of the equations in the system true.

For the system:

y=3x+1 and 2x+5y=22

The point (1,4) is a solution to the system.

(4)=3(1)+1 and 2(1)+5(4)=22

The standard form of an equation is when the equation looks like Ax+By=C. An example would be 3x+4y=20.

If a lot contains 48,000 square feet and is 240' wide, how deep is the lot?
lisabon 2012 [21]
We would assume the lot takes a rectangular shape. With that in mind. the area of the rectangular plot is 48, 000 and its width is 240. We only need to know the area of a rectangle which is L * W.  
So 48, 000 = L * 240 
L = 48, 000/ 240  
L = 200 
It is 200 square feet deep.
