How do you solve a system of equations by multiplying

Mathematics

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.

vlada-n [284]

Answer:

1330.808 euros

Step-by-step explanation:

Let's first calculate the total amount of kilograms,

for the first 60, we have to:

50 kg

4 hg = 0.5 kg

60 dag = 0.6

5 g = 0.005 kg

adding: 50 + 0.5 +0.6 + 0.005 = 51.105 kg per tree, but they are 60

51.105 * 60 = 3066.3

now for the other 20:

53 kg

2 hg = 0.2 kg

16 dag = 0.16

5 g = 0.005

adding: 53 + 0.2 +0.16 + 0.005 = 53.365 kg per tree, but they are 20

53,365 * 20 = 1067.3

in total it would be: 3066.3 + 1067.3 = 4133.6

they tell us that 1/5 is the quantity in liters:

4133.6 * 1/5 = 826.72 liters

so to calculate the earnings it would be:

2.65 * 826.72 - 860 = 1330.808

which means that in net earnings are 1330.808 euross
