Isolate the w. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, multiply 4/3 to both sides

(3/4)(4/3)(8w - 12) = 3(4/3)

8w - 12 = (12/3)

8w - 12 = 4

Isolate the w. Add 12 to both sides

8w -12 (+12) = 4 (+12)

8w = 4 + 12

8w = 16

Finally, to completely isolate the w, divide 8 from both sides

8w/8 = 16/8

w = 16/8

w = 2

2 is your answer for w

What do i do to find the value of an expression
Veseljchak [2.6K]

Answer:

A variable is a letter, for example x, y or z, that represents an unspecified number.

6+x=12

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.

If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Step-by-step explanation:

6z+4x=?

 

Solution: Replace x with 3 and z with 2 to evaluate the expression.

6z+4x=?

6⋅2+4⋅3=?

12+12=24

Hope this helps @(^_^)@
