How can you solve problems involving equivalent expressions.
Answers
Step-by-step explanation:
Step 1
Check for the distributive property on each side of the equal sign. If present, complete the distributive property. There is no distributive property in our example.
Step 2
Check for combining like terms on each side of the equal sign. If present, combine all like terms on the same sign of the equal sign. There are no like terms present in our example.
Step 3
Collect all the variables on the same side of the equal sign. Do this by adding or subtracting the variable with its coefficient from both sides of the equation. Add or subtract based on whichever is opposite of the current operation. By subtracting 7.50x (subtracting is opposite of a positive 7.50x), we can move the x's on the same side of the equation. What you do to one side of the equation you must do to the other side to keep the equation equal.
Step 4
Collect all constants on the opposite side of the equation as the variable. You can do this by adding or subtracting the constant from both sides of the equation. Again, add or subtract based on whichever is the opposite of the current operation. The 12 is a positive 12 so we do the opposite operation, which would be subtracting 12.
