1 NAME DATE PERIOD Study Guide and Intervention Algebra: Equations An equation is a sentence in mathematics that contains an equals sign. The solution of an equation is the value that when substituted for the variable makes the equation true. Solve 23 y 29 mentally. Lesson y 29 Write the equation You know that 23 6 is Simplify. The solution is 6. What value of x is a solution of x 8 26? A. 16 B. 17 C. 18 D. 19 Substitute each value for x to determine which makes the left side of the equation equivalent to the right side. Replace x with 16. Replace x with 17. Replace x with 18. x 8 26 x 8 26 x false false true The value of 18 makes the equation true. So, the answer is C. Solve each equation mentally. 1. k g y a x r h 8. n x 10. h y f 90 Name the number that is the solution of the given equation h 10; 7, 17, n 11 4; 44, 55, 66 Glencoe/McGraw-Hill 21 Mathematics: Applications and Concepts, Course 2
2 NAME DATE PERIOD Study Guide and Intervention Solving Addition and Subtraction Equations Remember, equations must always remain balanced. If you subtract the same number from each side of an equation, the two sides remain equal. Also, if you add the same number to each side of an equation, the two sides remain equal. Solve x Check your solution. x 5 11 Write the equation. 5 5 Subtract 5 from each side. x 6 Simplify. Check x 5 11 Write the equation Replace x with This sentence is true. The solution is t 12 Write the equation Add 12 to each side. 27 t Simplify. Solve 15 t 12. Check your solution. Check 15 t 12 Write the equation Replace t with This sentence is true. The solution is 27. Solve each equation. Check your solution. 1. h m p y 8 5. w k r z b c j v w y f n 12 Glencoe/McGraw-Hill 190 Mathematics: Applications and Concepts, Course 2
3 NAME DATE PERIOD Study Guide and Intervention Solving Multiplication Equations If each side of an equation is multiplied by the same number, the resulting equation is equivalent to the given one. You can use this property to solve equations involving multiplication and division. Solve 45 5x. Check your solution. 45 5x Write the equation x 5 5 Divide each side of the equation by 5. 9 x Check 45 5x Write the original equation. 45 5(9) Replace x with 9. Is this sentence true?
