Question

Can someone explain this to me? 
3x+2(5x-7) 
I'm supposed to simplify the expression

563blackghost · Answer

We are given the equation...

$\huge{3x+2(5x-7)}$

We see that we would work in the terms of PEMDAS as well as what we know on simplifying equation with variables....The first thing we do is distribute the 2 into the equation in the paranthesis....

$\huge\color{orange}{3x+((5x \times 2)-(2 \times 7))}$

What would that equal?

vuriffy · Answer

3x + (5x * 2) - (2*7)
What is 5 * 2 and 2*7?

563blackghost · Answer

$\large{Remember}$: When multiplying a variable with a real number you will only multiply the real number it contains with it...

Ex. 

5x times 3 = (5 x 3)x = 15x

Awh, I was going to say that with (5*2)x.
