Solve the equation.

78=-2(m+3)+m

-1/3m-7=5

1/4y+9=1/2

x-9=-6x+5

x+9=5(4x-2)

Can you please show me how you got your answer.

  • Pre-Algrebra -

    1. first distribute
    2(m+3) = 2m + 6

    then add like terms together

    3m + 6 = 78

    then sub. 6

    3m= 72

    last divide by 3
    m=24
