| Given that 2š„ + 7 = 27 and 3š„ + 1 = 28, does 2š„ + 7 = 3š„ + 1? Explain. | No |
| Is ā5 a solution to the equation 6š„ + 5 = 5š„ + 8 + 2š„? Explain. | If we replace ą¢ with the number ąµą«, then the left side of the equation is ą« Ś) ąµą«) + ą« = ąµą«ą« + ą« = ąµą«ą«, |
| Does š„ = 1.6 satisfy the equation 6 ā 4š„ = ā š„ 4? Explain. | If we replace ą¢ with the number ą«. ą«, then the left side of the equation is ą«ąµą«Śą« = ą« .ą«ąµą«. ą« = ąµą«. ą«, and the right side of the equation is ąµ ą«. ą« ą« = ąµą«. ą«. Since ąµą«. ą« = ąµą«. ą«, then ą¢ ą« .ą« = is a solution of the equation ą« ąµ ą«ą¢ = ąµą¢ ą« |
| Does š„ = 5 satisfy the equation above? Explain. | If we replace ą¢ with the number ą«, then the left side of the equation is ą«(ą« + ą«) = ą«(ą«) = ą«ą«”, and the right side of the equation is ą« + ą«Śą« = ą« + ą¢ą« = ą«ą« + ą« = ą«ą«”. Since ą«ą«” = ą«ą«”, then ą¢ ą« = is a solution of the equation ą«(ą¢ą« = (ą« + ą¢.ą« |
