About "Solving equations with variables on both sides"

Solving equations with variables on both sides :

To solve equations with variables on both sides, we have to bring the variables to the left side of equal sign and the numbers which or not having the variables, that is constants to the right side of equal sign.

Solving Equations with Variables on Both Sides - Steps

Step 1 :

Use the Distributive Property to remove the grouping symbols.

Step 2 :

Simplify the expressions on each side of the equals sign.

Step 3 :

Use the Addition and/or Subtraction Properties of Equality to get the variables on one side of the equals sign and the numbers without variables on the other side of the equals sign.

Step 4 :

Simplify the expressions on each side of the equals sign.

Step 5 :

Use the Multiplication or Division Property of Equality to solve.

If the solution results in a false statement, there is no solution of the equation.

If the solution results in an identity, the solution is all numbers.

Solving Equations with Variables on Both Sides -Examples

Example 1 :

Solve the following equation. Then check the solution.

5t - 9  =  -3t + 7

Solution :

5t - 9  =  -3t + 7

In order to get rid of -3t, we have to add 3t on both sides.

5t + 3t - 9  =  -3t + 3t + 7

8t - 9  =  7

In order to get rid of -9, add 9 on both sides

8t - 9 + 9  =  7 + 9

8t  =  16

Divide by 8 on both sides

8t/8  =  16/8

t  =  2

Hope this helps you understand better!

step-by-step explanation:

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
