We call this distributing a over b + c.
B) We subtract y 3 from both sides of the first equation to get the second. Apago PDF Enhancer Warning: Dividing Both Sides by an Expression That Might Be Zero Not every operation that we can perform on both sides of an equation leads to an equivalent equation. If you divide both sides by an expression that could be equal to zero, then you might lose some solutions. Example 4 What operation transforms the first equation into the second equation? Explain why this operation does not produce an equivalent equation.
You can verify that t = 2 is a solution to the two equations t2 = 4 and t3 = 8. Are these equations equivalent? Solve the equations in Exercises 35–46. 13. 2x + 3 = 13 15. x + 5 = 20 3 Apago PDF Enhancer 35. 5x + 12 = 90 14. 2(x + 3) = 13 16. x+5 = 20 3 36. 10 − 2x = 60 x+2 37. 3(x − 5) = 12 38. In Exercises 17–24, is the second equation the result of a valid operation on the first? If so, what is the operation? 39. 3x = 18 40. −2y = 14 41. 3z = 22 42. x + 3 = 13 17. 3 + 5x = 1 − 2x 3 + 7x = 1 18.
