Solve the system of equations by substitution. y = 8 X – 2y + 3z = 3 3x + 3y – 2z = 15

Dafna1 [17]

Answer:

Solving systems of equations with 3 variables is very similar to how we solve systems with two variables. When we had two variables we reduced the system down

to one with only one variable (by substitution or addition). With three variables

we will reduce the system down to one with two variables (usually by addition),

which we can then solve by either addition or substitution.

To reduce from three variables down to two it is very important to keep the work

organized. We will use addition with two equations to eliminate one variable.

This new equation we will call (A). Then we will use a different pair of equations

and use addition to eliminate the same variable. This second new equation we

will call (B). Once we have done this we will have two equations (A) and (B)

with the same two variables that we can solve using either method. This is shown

in the following examples.

Example 1.

3x +2y − z = − 1

− 2x − 2y +3z = 5 We will eliminate y using two different pairs of equations

5x +2y − z = 3

Solve equation using SQAURE ROOTS, show work. Round to the nearest hundredth if needed

ivann1987 [24]

Answer:

x=8, x=4

Step-by-step explanation:

Add 4 to both sides

$(x-6)^2=4$

Square root

$(x-6)= \sqrt{4}$

x - 6 = ±2

x = 8

OR x = 4

So, x=8 or x=4

Area of circle 1 = πr²
Area of circle 1 = π (10)²
Area of circle 1 = 100π km²

Area of circle 2 = πr²
Area of circle 2 = π (5)²
Area of circle 2 = 25π km²

Number of times the bigger circle is greater than the smaller circle
$\dfrac{100 \pi }{25 \pi } = 4$

------------------------------------------------------------------------------------
Answer: The big circle is 4 times greater than the small circle.
