Don’t trip just use the distributive property. -5(3x-2)= -50 which would end up being -15x -7 = -50; then add 7 to both -7 which then they will cancel out and add 7 to -50 which equal -43 so x = -43

Answer:

x = 4

Step-by-step explanation:

Okay so for this equation we have this:

-5(3x - 2)= - 50

because the 3x and -2 are in a parentheses that shows we have to multiply -5 we do like this:

(3x(-5) - 2(-5)) = -50

-15x + 10 = -50

Since we want to get rid of the 10 we are going to subtract 10 from both sides:

-15x + 10 = -50

       - 10    -10

Since we are actually going to add -10 to -50 its going to look more like this:

-15x = -60

Now we are going to divide -15 from -15x and -60 in order to segregate -15 from x:

-15x/-15 = -60/-15

x = 4

Now we double check our work by placing 4 where x once was:

-5(3(4) - 2)= - 50

-5(12 - 2) = -50

-60 + 10 = -50

-50 = -50

Hope this helps

What must be added to x - y to obtain y-x?
Lera25 [3.4K]
To make x-y reasonable, you must make x the same value as y. It is the same as y-x. But a different variable order. For example x= 6 and y=9, and x - y is unreasonable, to make it reasonable, you must add 3 more to x to make it the way of y - x. So, your answer is just like 9-9 or 10-10 or any other subtraction equation with equal value, you don’t have to know what the variables equal, you just have to take an example and try it, that’s all you need to do to get out of the tricky problems. Hope this helps and have a great night of sleep :))

5x + 9 = x - 23 find X​
Doss [256]

5x + 9 = x - 23

move x to the other side

sign changes from +x to -x

5x-x+9= x-x-23 ( combine like terms)

5x-x+9= -23

4x+9= -23

move -9 to the other side

4x+9-9= -23-9

4x= -23-9

4x= -32

divide both sides by 4 to get x by itself

4x/4= -32/4

answer:

x= -8

Hey guys I need help with this exercise!!! PLZZZ HELP!
IRISSAK [1]

Answer:

365

Step-by-step explanation:

The discount is 30 %

That means we pay 70 %

original price * 70% = 255.50

Change to decimal form

original price * .70 = 255.50

divide each side by .70

original price * .70/.70 = 255.50/.70

original price =365
