    Carlos was asked to write an equivalent equation to 2x/5 = 1 - x. he wrote it as 2x = 1 - 5x. do you agree with his conclusion? explain your answer for x

    Cross multiply
    2x/5 = 1 - x
    2x = 5(1 - x)
    2x = 5 - 5x

    I disagree with his conclusion. He forgot to multiply the 5 through to both terms
