(7x +6) - (5x - 4) = 180
BartSMP [9]

Answer:

x= 85

Step-by-step explanation:

(7x+6)-(5x-4)=180

There is a negative 1 between the two parenthesis

-1(5x-4)

-5x+4

Now plug it back into the equation and take out the parenthesis

7x+6-5x+4= 180

2x+10=180    Now we can solve

    -10  -10

2x= 170

2x/2 = 170/2

x= 85

I hope this helps! :)
