We want to determine x from the expression
b(5px - 3c) = a(qx - 4)

Expand each side.
5bpx - 3bc = aqx - 4a

Subtract aqx from each side.
5bpx - aqx - 3bc = - 4a
x(5bp - aq) - 3bc = - 4a

Add 3bc to each side.
x(5bp - aq) = 3bc - 4a

Divide each side by 5bp - aq
x = (3bc - 4a)/(5bp - aq)

Answer: $x= \frac{3bc-4a}{5bp-aq}$

Answer:

x = -5

Step-by-step explanation:

In both questions you want to get the x alone.

-3x + (-6) = 9

First you want to add 6 to both sides so you'll be left with:

-3x = 15

Next, you want to divide both sides by -3 and you'll get:

x = -5

-4x + (-12) = 8

You want to do the same thing as the first one so you'll add 12 to both sides:

-4x = 20

Then, you will divide both sides by -4 and get:

x = -5

A student solved the equation 2x+6=12 using algebra tiles. incorrectly says the solution is 9. Solve the equation. What mistake

alexdok [17]

Instead of subtracting 6 from 12 then dividing they added 6 to 12 & ended up with 18. 18 by 2 is 9.

What is 1000 k = to but it has to be a gram .any get it cause I don't help me

denpristay [2]

You need to convert 1000kg to grams? There are 1000g $\frac{1000g}{kg}$
Now what you need to do is multiply the number of kg you have by your conversion fractions, making sure that grams is on top so you end up with grams in your answer: $\frac{1000kg}{g}$ * $\frac{1000g}{kg}$

Kg cancel, and you are left with 1,000,000g
This means that there are 1,000,000g in 1000kg
Hope this helps!
