Algebra II Recipe: Solving Linear Equations
By G Redden
- Do the distributive property on each side.
- Combine like terms on each side.
- Add or subtract to get the variable terms on the same side. The side of the largest coefficient is best.
- Add or subtract to move the number term to the opposite side of the variable term.
- Multiply or divide to move the coefficient to the opposite side of the variable term.
1.
7x - 29 = -15
2.
x - 30 = 6 - 2x
3.
4(-3x + 1) = -10(x - 4) - 14x
4.
-4(3 + x) + 5 = 4(x + 3)
- Multiply each term in the equation by the LCD.
- Collect like terms and follow the steps above in part A.
5.
(1/3)x + (1/4) = x - (1/6)
- Multiply each term in the equation by 10, 100, or 1,000 to make all numbers whole.
- Only numbers on the outside of parentheses get multiplied by the 10, 100, or 1,000.
- Collect like terms and follow the steps above in part A.
6.
3.1(x + 2) - 1.5x = 5.2(x - 4)
- The answer is No Solution, if a false statement is the result.
- The answer is All Real Numbers, if a true statement is the result.
7.
3(x - 1) = 5x + 3 - 2x
