Solve using the multiplication principle Don't forget to preform a check 11x=-99
Would the answer be -9?
Right.
To solve the equation 11x = -99 using the multiplication principle, we want to isolate the variable x.
The multiplication principle states that if we multiply both sides of an equation by the same non-zero number, the two sides remain equal.
In this case, we want to get rid of the coefficient 11 next to x. To do this, we can divide both sides of the equation by 11:
(11x)/11 = (-99)/11
Simplifying, we get:
x = -9
So, the solution to the equation 11x = -99 is x = -9.
To perform a check, we substitute the value of x back into the original equation:
11(-9) = -99
-99 = -99
Since both sides of the equation are equal, we can conclude that x = -9 is the correct solution.
