3х - у = -3<br>х+у= -1 using elimination <br>method

Vesnalui [34]

Answer:

Your solution is (-1, 0)

Step-by-step explanation:

3x - y = -3

x + y = -1

The elimination method <em>eliminates</em> one variable at a time to find the other variable.

Here we can see that the y variable will naturally be eliminated.

3x - y = -3

x + y = -1

--------------

4x = -4

Divide both sides by 4 to isolate x.

x = -1

Now plug this value back into one of the equations.

3(-1) - y = -3

Multiply.

-3 - y = -3

Add 3 to both sides.

-y = 0

Divide both sides by -1.

y = 0

Your solution is (-1, 0)

Check this solution by plugging these values into the second equation.

-1 + 0 = -1

-1 = -1

Your solution is correct.

Hope this helps!

It is known that 5< x< 8. find all possible values of the expression, 6x, -10x,x-5,3x+2

Nuetrik [128]

Answer:

Part 1) $30< 6x< 48$

Part 2) $-80< -10x< -50$

Part 3) $0$

Part 4) $17< 3x+2< 26$

Step-by-step explanation:

we know that

$5< x< 8$

The solution for x is the interval ----> (5,8)

All real numbers greater than 5 and less than 8

Part 1) Find all possible values of the expression 6x

For x < 8

The expression value is 6x < (6)(8) -----> 6x < 48

For x > 5

The expression value is 6x > (6)(5) -----> 6x > 30

therefore

$30< 6x< 48$

Part 2) Find all possible values of the expression -10x

For x < 8

The expression value is -10x > (-10)(8) -----> -10x > -80

For x > 5

The expression value is -10x < (-10)(5) -----> -10x < -50

therefore

$-80< -10x< -50$

Part 3) Find all possible values of the expression x-5

For x < 8

The expression value is x-5 < 8-5 -----> x-5 < 3

For x > 5

The expression value is x-5 > 5-5 -----> x-5 > 0

therefore

$0$

Part 4) Find all possible values of the expression 3x+2

For x < 8

The expression value is 3x+2 < 3(8)+2 -----> 3x+2 < 26

For x > 5

The expression value is 3x+2 > 3(5)+2 -----> 3x+2 > 17

therefore

$17< 3x+2< 26$
