3(x-7) = 138 + 3x First multiply
3x-21 = 138 + 3x subtract 3x from both sides
-21 = 138
This is a false statement because -21 does not equal to 138 so the answer is no solution.

Answer:
Option B, x = 20
Step-by-step explanation:
<u>Step 1: Make an equation</u>
The values of 65 degrees and (3x + 5) are equal.
65 = 3x + 5
<u>Step 2: Subtract 5 from both sides</u>
65 - 5 = 3x + 5 - 5
60 = 3x
<u>Step 3: Divide both sides by 3</u>
60 / 3 = 3x / 3
<em>20 = x</em>

Answer: Option B, x = 20
Answer:
5 is the common ratio for your numbers
Here is the Distributive Property made simple.
When you have a number outside a number or numbers inside parentheses, you multiply whatever is inside the parentheses by the number outside the parentheses.
3( 7 + 5 +4) becomes 3 x7 + 3x5 +3 x 4
0r 21 +15 +12
You multiplied each of the numbers by the 3
If there is a variable, that is distributed also
3y(4 + 6) becomes 12 y +18y
