Answer:

-5x+y=-22

Add -y to both sides.

-5x+y+(-y)=-22+(-y)

-5x=-y-22

Divide both sides by -5

-5x/-5=-y-22/-5

x=1/5y+22/5

which is your answer^

Step-by-step explanation:

-6x+5y=-15

Add -5y to both sides.

-6x+5y+(-5y)=-15+(-5y)

-6x=-5y-15

Divide both sides by -6

-6x/-6=-5y-15/-6

x=5/6y+5/2

which is the answer to the first set of questions.

In the diagram below segment DEF is shown(since all three letters are shown, they are collinear). If DE=3x+2, EF= x+5, and DF= 2

amm1812

The value of $x$ is 4.

By Geometry, we know that line segment $DF = DE + EF$ , which is equivalent to:

$DF = 3\cdot x + 2 + x + 5$

$DF = 4\cdot x + 7$ (1)

Now we solve algebraically the resulting expression.

If we know that $DF = 23$ , then we solve the equation for $x$ :

$4\cdot x + 7 = 23$

$4\cdot x = 16$

$x = 4$

The value of $x$ is 4.

Answer:

C) 75 + 50x = 25 + 70x

Step-by-step explanation:

ABC Tech:

$50 an hour. So,for x hours= 50 * x = 50x

Service charge = 75 + 50x

Tech Squad:

$70 an hour. So,for x hours= 70 * x = 70x

Service charge = 25 + 70x

C) 75 + 50x = 25 + 70x

50x - 70x = 25 - 75

-20x = -50

x = -50/-20

x =5/2 = 2 $\frac{1}{2}$ hours
