Answer:
x = -103/70 or approximately -1.47
Step-by-step explanation:
First, what I would do is get rid of the denominator, 2. You do this by perming the inverse operation to both sides, so you multiply both sides by 2.
Now your equation is: 70(4x+6) = 8
Next what I did was distribute the 70 inside the parentheses:
280x + 420 = 8.
Then you subtract 420 from both sides:
280x = -412
To get x by itself, you have to divide both sides by 280:
x= -412/280 , which simplifies to -103/70 , or can be written as an approximation of -1.47 (rounded to nearest hundredth)
This number looks nasty, but I checked my work so it should be right :)
