First u have to factor the expression

2(9-(x+(x-5))x 8 - 2 x 28 - 2 x 28 - x)

next you have to remove the parenthesis and multiply

2(9 -(x + x - 5) x 8 - 2 x 28 - 2 x 28 - x) that's -2 x 28

2(9 -( x+ x - 5) x 8 - 56 - 2 x 28 - x)

 2(9 -( x + x -5) x 8 -56 -56 - x)

Check like terms

2(9 -(2x-5) x 8 -56 -56 - x)

multiply by 8

2(9 - (16x - 40) -56 -56 - x)

remove parenthesis

2(9 - 16x + 40 -56 -56 - x)

calculate  and collect like terms

2( -63 - 16x - x)

collect the like terms

2( -63 -17x)

your answer is: 2(-63 - 17x)

Answer:

The equation of line in the form of Ax + By = C is: \mathbf{4x+y=-17}

Step-by-step explanation:

We need to find the equation of line, having slope m = -4 and passes through point (-2,-9)

First we need to find slope and y-intercept of the line.

The slope is given i.e. m = -4

Now, we need to find the y-intercept

Using the point (-2,-9) and slope m = -4, y-intercept can be found using:

y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17

Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:

y=mx+b\\y=-4x-17

Now writing in form of Ax + By = C

y=-4x-17\\4x+y=-17

So, the equation of line in the form of Ax + By = C is: \mathbf{4x+y=-17}.

Follow the steps to solve for the variable in this two-step equation:
Ratling [72]

Answer:

x=2

Step-by-step explanation

5x-10=0

fist add 10 to both sides to cancel the -10 on the left side

5x=10

then divide both sides to cancel the 5 in front of the x and to get the x all by itself

x=2

and then you have your answer!
