91-3x= 64
-3x= -27
X= 9

Answer 2

To solve this equation, we need to isolate the variable x on one side of the equation. We can do that by using algebraic operations to simplify the equation.

Here are the steps to solve the equation (91-3x):4=16:

1. Start by multiplying both sides of the equation by 4 to eliminate the fraction:

(91-3x):4 x 4 = 16 x 4

This gives us:

91 - 3x = 64

2. Next, we want to isolate the term with x on one side of the equation. We can do that by subtracting 91 from both sides of the equation:

91 - 3x - 91 = 64 - 91

Simplifying the left-hand side:

-3x = -27

3. Finally, we can solve for x by dividing both sides of the equation by -3:

x = 9

Therefore, the solution to the equation (91-3x):4=16 is x = 9.
