4(x-2)=3(1.5+x)

Use Dis.Property
Combine like terms
Solve using inverse operations

I just don't understand!Please explain

  • Pre- Algebra -

    4x-8=4.5+3x
    4x-3x=4.5+8
    x= ....

  • Pre- Algebra -

    4 (x - 2) = 3 (1.5 + x)
    1) 4x - 8 = 4.5 + 3x Multiply the number outside the par. by the numbers inside the paranthesis. Distributive Property

    2) 4x = 12.5 + 3x Eliminate the (-8) from both sided by adding 8 to both sides. Combine like terms and inverse operations.

    3) x = 12.5 Get x on one side by subtacting 3x from both sides. Combine like terms and inverse operations.

    4) The check is up to you. The answer is x = 12.5.
