15h - 4 = 6
Two step problem

Answers

Answer:

h = 10/15

Step-by-step explanation:

Isolate the variable, h. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 4 to both sides of the equation:

15h - 4 (+4) = 6 (+4)

15h = 6 + 4

15h = 10

Next, divide 15 from both sides of the equation:

(15h)/15 = (10)/15

h = 10/15 or 0.667 (rounded)

Jerry solved the equation 2x-4=20 by adding four 1-tiles to each side. Explain why Jerry's method works.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the equation : 2x-4=20

By adding 4 1 - tiles to each side, this will eleminate the constant term on the left hand side where the Coefficient we wish to solve for lies. Hence, the same exact treatment given to data on the right hand side is done to the data in the left. Hence, the method will work as it will give ;

2x - 4 = 20

2x - 4 + 4 = 20 + 4

2x = 24 ( constant eliminated)

x = 24/4
