Solve the system of equations with elimination. Show ALL steps. x+3y=4
x-2y= -1
They are the same equation, you have to find out what x equals and what y equals THANK YO!!! :). NO DANG LINKS EITHER OR IMA MAKE SURE UR DELETED.

(1 , 1)

Step-by-step explanation:

x+3y=4

x-2y=-1

We can solve this system of equations using the elimination method. In this method there must be two identical variables ( which in this case there is, that variable being x ). If there are two identical variables you can subtract the two equations "eliminating" one of the variables. There is then only one variable in which you can solve for.

So first let's subtract the two equations

x + 3y = 4

- ( x - 2y = -1 )

remove parenthesis and apply negative sign

x + 3y = 4

-x + 2y = +1

0 + 5y = 5

We are now left with one variable in which we can solve for.

5y = 5

divide both sides by 5

y = 1

Next we want to find the value of x.

To do so we simply plug in the value of y into one of the equations and solve for x. Note that we could do this to either equation and we would get the same answer.

x + 3y = 4

y = 1

x + 3(1) = 4

multiply 3 and 1

x + 3 = 4

subtract 3 from both sides

x = 1

So x = 1 and y = 1

Therefore the solution to the system of equations is (1,1)

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
