Which expression shows the first step in simplifying 2x – 3(x + 2y) – 5(y – 7x)?
2x – 8(x + 2y) + (y – 7x)
2x – 3 – 5(3y – 6x)
2x – 3x – 6y – 5y + 35x
2x + 3x + 6y + 5y – 35x

Respuesta :

the first step is to apply the distributive law to the 2  parentheses
so its start with 2x - 3x - 6y -5y + 35

Answer:

the answer is 2x-3x-6y-5y+35x

Step-by-step explanation:

we know that for solving any equation we must use BODMAS rule which is the solving the bracket,division,multiplication,addition and subtraction.

in the following given expression we have [tex]2x-3(x+2y)-5(y-7x)[/tex] so we have to firstly open this bracket and for the first bracket we have to multiply both the terms inside the bracket with -3 and in the second bracket we have to multiply both the terms inside the bracket with -5 to obtain the resultant expression as 2x-3x-6y-5y+35x.
