Step-by-step explanation:
The golden rule for solving equations is to
A. Simplify each side of the equation by removing parentheses and combining like terms
B. Add/Subtract to isolate the term with the variable on one side
C. Use multiplication/division to isolate the variable
Let's assume we have the equation [tex]2x + 3x + (5\cdot2) = 35[/tex]
The first thing we need to do is solve inside the parentheses and combine like terms. 2x and 3x are like terms, so:
[tex]2x + 3x + 10 = 35\\\\5x + 10 = 35[/tex]
Now we have to subtract/add to isolate the term with the variable. To do this, we can subtract 10 from both sides.
[tex]5x + 10 - 10 = 35-10\\\\5x = 25[/tex]
Now we divide to isolate x.
[tex]5x \div 5 = 25\div5\\\\x = 5[/tex]
Hope this helped!
