Answer 3

To solve each equation, I will go through them one by one:

1. 3×x + 50 = 77:

Let's isolate the variable x by moving the constant term to the other side of the equation.

3×x = 77 - 50 3×x = 27

Now, divide both sides of the equation by 3 to solve for x:

x = 27/3 x = 9

So the solution for the equation 3×x + 50 = 77 is x = 9.

2. 100 - 24 ÷ c = 92:

Let's isolate the variable c by moving the constant term to the other side of the equation.

-24 ÷ c = 92 - 100 -24 ÷ c = -8

To get rid of the fraction, multiply both sides of the equation by c:

-24 = -8c

Now, divide both sides of the equation by -8 to solve for c:

c = -24 / -8 c = 3

So the solution for the equation 100 - 24 ÷ c = 92 is c = 3.

3. 3×x = 92 - 68:

To isolate the variable x, we will perform the necessary operations on both sides of the equation.

3×x = 92 - 68 3×x = 24

Now, divide both sides of the equation by 3 to solve for x:

x = 24/3 x = 8

So the solution for the equation 3×x = 92 - 68 is x = 8.

Therefore, the solutions for the given equations are:

x = 9, c = 3, x = 8.
