2x - 3 = 8
add 3 to both sides
2x = 11
divide both sides by 2
x = 5.5
Answer:
1 and -5
Step-by-step explanation:
0 divided by anything is 0
the numerator can equal zero if one factor =0
so
x-1=0
or
x+5=0
solving, we get x=1 or x=-5
Let's just say that "d" represents the variable for dogs. 3+5d
Step-by-step explanation:
i assume this is the question you asked me to look at.
Well, angle 116° and y are supplementary angles
therefore,116°+y=180°
y=180°-116°=64°
Now to find x
x+y+125+72=360°
x+64+125+72=360
x+261=360
x=360-261=99°
Solving for x.
Add by to both sides
Ax=c+by
Divide both sides by a
x=c+by
-------
a
