    a) x = 5

    b) x = 4

    Step-by-step explanation:

    a) 4x - 3 = 2x + 7 collect like terms

    4x - 2x = 7 + 3

    2x = 10 divide both sides by the coefficient of x

    x = 5

    b) 2x + 6 = 7x - 14 collect like terms

    2x - 7x = - 14 - 6

    -5x = - 20 divide both sidess by the coefficient of x

    x = 4
