Answer:

x=4

Step-by-step explanation:

First, you want to add the -3x and the -2x together to get -5x

-2x=-5x+12

then you're gonna add -5x to -2x

-2x+5x=12

that should get you

3x=12

divide both sides by 3

3x/3=12/3

that should get you x=4

I believe it is asking for x so I will be finding the value of x.

X = 4, work is shown below:

−2x=−3x+12−2x

Step 1: Simplify both sides of the equation.

−2x=−3x+12−2x

−2x=−3x+12+−2x

−2x=(−3x+−2x)+(12)(Combine Like Terms)

−2x=−5x+12

−2x=−5x+12

Step 2: Add 5x to both sides.

−2x+<u>5x</u>=−5x+12+<u>5x</u>

3x=12

Step 3: Divide both sides by 3.

3x/3 =1 2/3

x=4

ira [324]

The number of miles covered every evening obtujwd using a <em>system of equation</em> is 15 miles.

<u>Let the number of miles per evening</u> = m

  • Number of days = 5

  • Number of miles per morning = 8 miles

  • Total miles covered = 115 miles

<u>Using the expression below :</u>

<em>Number of days(miles per morning + miles per evening) = 115 miles </em>

5(8 + m) = 115

40 + 5m = 115

5m = 115 - 40

5m = 75

m = 75 / 5

m = 15 miles

Therefore, the Number of miles covered per evening is 15 miles.

Find the inverse of the function.<br> y=3x–5
PIT_PIT [208]

Step-by-step explanation:

it means that x has now to be the result variable, and y the input variable.

so,

y = 3x - 5

y + 5 = 3x

x = (y + 5)/3

and as a final touch, to make the inverse a "normal function", we rename x to y and y to x and get

y = (x + 5)/3

as the inverse function
