What is the solution of the system? use the elimination method. {4x+2y=182x+3y=15

and

Step-by-step explanation:

The system of equations:

Using the elimination methos, i want to eliminate the x first. for this, we multiply the second equation by 2, and then we subtract it from the first equation.

Multiplying the second equation by 2:

and subtracting this from the first equation:

which is:

this gives the following:

We just eliminated the variable to find . Finally we substitute the value of in any of the equations to find .

using

the solution is and

a

b

d

step-by-step explanation:

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
