Which of the following should be done to both sides of the equation −6x=48 to solve the value of x ?
add 6
multiply by −6
divide by −6
divide by 6
To solve for x in the equation −6x = 48, you need to isolate x on one side of the equation. To do that, you can perform the opposite operation of what is currently applied to x. Since x is multiplied by −6, you should divide both sides of the equation by −6, which is the inverse operation of multiplication.
So, the correct action to take is:
divide by −6
When you divide both sides by −6, you get:
−6x / −6 = 48 / −6
Which simplifies to:
x = -8
So the value of x is -8.
What's the answer
Apologies for the confusion in my previous response. The answer to the equation −6x = 48, when you divide both sides by −6, is:
x = 48 / (−6)
x = −8
So the value of x is indeed -8.
No choose one of the options I gave u
My apologies for misunderstanding your initial question. If we need to choose from the options you provided to solve the equation −6x = 48, the correct option to isolate x would be:
divide by −6
When you divide both sides by −6, you'll find the value of x. Here's the calculation:
−6x / (−6) = 48 / (−6)
x = −8
Thus, the solution for x is −8 after dividing both sides by −6.
Which of the following should be done to both sides of the equation x12=6 to solve the value of x ?
divide by 12
divide by 12
multiply by 6
multiply by 6
multiply by −12
multiply by 12
To solve for x in the equation x/12 = 6, you should multiply both sides by 12 because x is currently being divided by 12. Multiplying both sides by 12 is the inverse operation and will isolate x on one side of the equation.
So, the correct operation to perform is:
multiply by 12
When you multiply both sides by 12, the equation becomes:
(x/12) * 12 = 6 * 12
Which simplifies to:
x = 72
Therefore, the value of x is 72 after you multiply both sides of the equation by 12.
What is the solution of the equation −x2.9=−3 ?
8.7
−87
−8.7
87
To solve the equation -x/2.9 = -3, you want to isolate x by multiplying both sides of the equation by -2.9. Here's the solution:
-x/2.9 = -3
-x = -3 * (-2.9)
-x = 8.7
Now to solve for x, we need to multiply by -1 since -x = 8.7 implies that x is the negative of 8.7:
x = -8.7
Therefore, the correct answer is:
-8.7
