    a=1

    Step-by-step explanation:

    a+3=2a+2

    Take away 3 from both sides

    a=2a-1

    Take away 2a from both sides

    -a=-1

    Multiply by - 1

    a=1

    a + 3 = 2a + 2

    move 2a to the other side

    sign changes from + 2a to - 2a

    a-2a+3 = 2a-2a + 2

    a-2a+3=2

    -a+3=2

    move 3 to the other side

    -a+3-3 = 2-3

    -a = 2-3

    -a = - 1

    mutiply both sides by - 1 to get + a

    (-1) (-a) = (-1) (-1)

    Answer:

    a = 1
