Can anyone check this answer out for me...
2(5-6y)
= 2 x 5 , 2 x -6
= 10 - 12y
or should the 12y appear before the 10 ???
am not sure of the rule... thanks
10-12y is correct.
It may also be written as -12y+10. There is no RULE that I know of that says the equation MUST be written one way or the other; however, most people prefer to write the variable (y term) first with the number following. Having said that, most people don't like to start an equation with a negative term. In my opinion, take your pick.
To simplify the expression 2(5 - 6y), you need to apply the distributive property, which states that when multiplying a number by an expression inside parentheses, you need to multiply the number by each term inside the parentheses.
Here's the step-by-step process:
1. Start by distributing the 2 to each term inside the parentheses:
2 * 5 - 2 * 6y
2. Multiply 2 by 5 and 2 by -6y:
10 - 12y
Therefore, the simplified form of 2(5 - 6y) is 10 - 12y.
There is no rule that specifies whether the term with the variable should appear before or after the constant term. The order of the terms does not affect the value of the expression; it only affects the way the expression is written. So, both 10 - 12y and -12y + 10 are valid ways to represent the same expression.
