Question

An equation is shown below:

Answer 1

Multiple 6 with numbers inside paranthesis:
12x - 66 + 15 = 21
add 66 fhen substrack 15 from both sides :
12x = 72 divide both sides with 12:
x = 6

Answer 2

Answer:

x = 6

Step-by-step explanation:

Given: 6(2x - 11) + 15 = 21

Step 1: Use the distributive property and simplify.

12x - 66 + 15 = 21

12x -51 = 21

Step 2: Isolate the variable and constants.

Add 51 from both sides, we get

12x - 51 + 51 = 21 + 51

12x = 72

Step 3: Dividing both sides by 12, we get

x = 72/12

x = 6

The value of x = 6.
