Using the distributive property, you can distribute the 7 to y and -4. In other words, multiply the number outside of the parenthesis by each of the numbers in the parentheis. 7*y+7*-4 =7y-28
To find an equivalent expression to this, use the distributive property. The distributive property means to multiply the term outside the parentheses by each term on the inside.
7 • y = 7y 7 • -4 = -28 It's a negative 4 since it has a minus sign in front of it.
7y - 28 is what we get from this. This can not be simplified further so it is the final answer.
