Question

2(x+2)=-(7x+6) Answer: find x and show work.

Answer 1

$2(x+2)=-(7x+6)\\ 2x+4=-7x-6\\ 9x=-10\\ x=-\dfrac{10}{9}$

Answer 2

To find the value of x in the equation 2(x+2)=-(7x+6), we need to get x by itself. We can do this by evaluating each side of the equation.

2(x+2) = -(7x+6)

First we must do multiplication (since we can't simplify the parenthesis). We must note that the - sign in front of the left expression is the same as -1.

2x + 4 = -7x - 6

Now we want to get the x's on one side and the numbers on the other.

9x = -10

We want to have a singular x, so:

x = -10/9
