QuestionAnswer
Given that 2𝑥 + 7 = 27 and 3𝑥 + 1 = 28, does 2𝑥 + 7 = 3𝑥 + 1? Explain. No
Is −5 a solution to the equation 6𝑥 + 5 = 5𝑥 + 8 + 2𝑥? Explain. If we replace ࢞ with the number െ૞, then the left side of the equation is ૟ ڄ) െ૞) + ૞ = െ૜૙ + ૞ = െ૛૞,
Does 𝑥 = 1.6 satisfy the equation 6 − 4𝑥 = − 𝑥 4? Explain. If we replace ࢞ with the number ૚. ૟, then the left side of the equation is ૟െ૝ڄ૟ = ૟ .૚െ૟. ૝ = െ૙. ૝, and the right side of the equation is െ ૚. ૟ ૝ = െ૙. ૝. Since െ૙. ૝ = െ૙. ૝, then ࢞ ૟ .૚ = is a solution of the equation ૟ െ ૝࢞ = െ࢞ ૝
Does 𝑥 = 5 satisfy the equation above? Explain. If we replace ࢞ with the number ૞, then the left side of the equation is ૜(૞ + ૚) = ૜(૟) = ૚ૡ, and the right side of the equation is ૜ + ૞ڄ૜ = ૜ + ࢞૜ = ૚૞ + ૜ = ૚ૡ. Since ૚ૡ = ૚ૡ, then ࢞ ૞ = is a solution of the equation ૜(࢞૜ = (૚ + ࢞.૜
Is 𝑥 = −8 a solution of the equation above? Explain. and the right side of the equation is ૜ + (െૡ (ڄ ૜ = ૜ + ࢞૜ = െ૛૝ + ૜ = െ૛૚. Since െ૛૚ = െ૛૚, then ࢞ = െૡ is a solution of the equation ૜(࢞૜ = (૚ + ࢞.૜ +
