Solving Algebraic Expressions
solve = find the value of the variable
* to solve for an unknown variable we use inverse operations on both sides of the equal sign. Remember to use the reverse order of PEMDAS.
Combining Like Terms:
Same variable Example: 4/3x and 85x
25y and 21y
Same variable product Example: 0.5xy and 0.23xy
All constants Example: 42 and 0.3
Dealing with variables on both sides of the equation:
Use inverse operations to move the variables to one side of the equation.
Example: 3y + 5 = 7y + 2
Hint: Subtract 3y from both sides of the equation.
Alternative: Subtract 7y from both sides of the equation.
