How do you solve a system of equations by multiplying

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.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
