Step-by-step explanation: First combine like terms:10x-18=6(x+3) Second: Distribute> 10x-18=6(x+3) 10x-18=6x+18 Third: Add 18 to both sides of the equation(Addition) 10x-18+18=6x+18+18 Fourth: Simplify (Addition) 10x=6x+36 Fifth: Subtract 6x from both sides of the equation 10x-6x=6x+36-6x 6th: Combine like terms 4x=36 7th:divide both sides by 4

4x/4=36/4 LAST STEP: divide the numbers

Hope this helps:)

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
