First group the coefficients together on their side of the equal sign.
-x + 3x = 2x.
Then, since it is a positive number, subtract it from that side and the other side.
On the other side, the x becomes -x.
Add the 6 from the other side to the 8 to make 14.
14 = -x
Divide both sides by -1, to get the answer.
x = -14
As a fraction = 1*83/100
As an improper fraction = 183/100
It's 8.00 + 0.09 + 0.07 = 8.97
Answer:
d = 24
Step-by-step explanation:
The external angle (98°) is equal to the sum of the opposite internal angles (2d°, (2d+2)°). This gives you an equation you can solve for d.
98 = 2d + (2d+2)
96 = 4d . . . . . . . . . . . . subtract 2, collect terms
24 = d . . . . . . . . . . . . . divide by 4
