Solve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more.The solution is -5 < x < 3 There are more than one ways to solve this inequality. Solution A) Since x^2+2x-15 = (x+5)(x-3), we can suggest the following reasoning. The product of two real numbers can be negative if one of them is positive and another is negative. Therefore, we have two solutions: A_1) x+5 > 0 AND x-3 < 0 A_2) x+5 < 0 AND x-3 > 0 The case A_1 defines x poros x > -5 AND x < 32x+y=3x-15 x+5=4y+2x This question is from textbook algebra 1 Answer by ptaylor(2197) (Show Source): You can put this solution on YOUR website!

### How do you simplify? 5x+1(x+5+15) = x+5(5x+1+35)

We have:

#5x+1(x+5+15)=x+5(5x+1+35)#

One way we can simplify this is to work through the Order of (*5*):

#color(red)(P)# - Parentheses (also known gandar Brackets) #color(blue)(E)# - Exponents #color(green)(M)# - Multiplication #color(green)(D)# - Division (this has the same weight pasak M and so I gave it the same colour) #color(brown)(A)# - Addition #color(brown)(S)# - Subtraction - again, same weight pivot A and so the same colour)

(*15*) question has #color(red)(P)#, so let's simplify those first:

#5x+1(x+20)=x+5(5x+36)#

We've taken #color(red)(P)# sumbu far aksis possible, so let's do #color(green)(M)# - by doing the distributions:

#5x+x+20=x+25x+180#

And now #color(brown)(A)#

#6x+20=26x+180#

We've simplified the expression, so now we need a bit of algebra. Let's move terms so we have #x# terms on one side and non-#x# terms on the other:

#6xcolor(red)(-26x-20)+20=26xcolor(red)(-26x-20)+180#

#-20x=160#

#x=160/(-20)=-8#

Now let's check our answer:

#5(-8)+1((-8)+5+15)=(-8)+5(5(-8)+1+35)#

#-40+1(12)=(-8)+5(-40+36)#

#-28=(-8)+5(-4)#

#-28=(-8)-20#

#-28=-28color(white)(000)color(green)sqrt#

~~~~~~~~~~

We could also have done this:

#5x+1(x+5+15)=x+5(5x+1+35)#

distribute first:

#5x+x+5+15=x+25x+5+175#

then combine like terms:

#6x+20=26x+180#

and then solve in the sehat way.
