How do you do equations on both sides.

Answers

If you give an example of a problem you are having trouble with, I can help walk you through it.
hello , to do equation on bother sides; these are the steps i use personally
e.g. 
5x-4=2x+14
you would subtract 2x from both sides so it will simply to...
3x-4=14  (do the opposite to the 4 in this case it is subtract and the opposite is add so you would add 4 to the 14 as following)
3x=14+4 
3x=18 
(divide 18 by 3 )
x=6

A=h(a+b)/2 solve for a

Answers

Answer:

2A/h - b =a

Step-by-step explanation:

A=h(a+b)/2

Multiply each side by 2

2A =h(a+b)/2*2

2A=h(a+b)

Divide each side by n

2A/h = h(a+b)/h

2A/h = a+b

Subtract b from each side

2A/h - b =a+b-b

2A/h - b =a

Answer:

((2A)/h)- b=a

Step-by-step explanation:

First get the 2 to the left by multiplying each side by 2. Then, get h to the right by dividing each side by h. Lastly, subtract b from each side.

Simplify the expression using the distributive property 9(4y-7)

Answers

The simplified expression using the distributive property is 36y - 63

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Using the distributive property, we can simplify the expression 9(4y - 7) as follows:

9(4y - 7) = 9 * 4y - 9 * 7

= 36y - 63

Hence , the simplified expression is 36y - 63
