Question

how would do you do expressions like 5(2x+6)=-4(-5-2x)+3x

Answer 1

5(2x+6)=-4(-5-2x)+3x

10x + 30 = 20 + 8x + 3x

30 - 20 = 11x - 10x
10 = x

Answer 2

First, you need to distribute with the two different parentheses.
5(2x)+5(6) = -4(-5) + -4(-2x) + 3x.
When you multiply, you get

10x + 30 = 20 + 8x + 3x

combine like terms

10x + 30 = 20 + 11x

Now, you need to get x alone in order to solve it. so, you subtract 20 from both sides to get the 11x alone. Now you have

10x + 10 = 11x

now subtract 10x from both sides

10 = 1x

divide by one

10=x
x=10

And there's your answer. Hope I helped!

Answer 3

5*(2x+6)= -4*(-5-2x)+3x

10x+30=20+8x+3x

10x+30=20+11x

10x-11x=20-30

-x=-10 Multiply with -1

x=10
