Solving 2 Step Eqns
Solve:
2x + 8 = 28
- 8 from both sides
divide 2
x = 10
8(x - 2) + 6 = 14
Distribute by multiplying
Combine like terms
Solve
x = 3
Give 2 answers for this:
x < -3
Any numbers less than or equal to -3
sqrt 49

What is the coefficient in the expression:
-3f - 8
-3
.8x - .42 = 1.62
+ .42
/ .8
x = 2.55
6m + 4 - 2m = 5m + 2
Combine like terms & solve.

-5h + 8 > -2
h < 2
What is the cubed root of 8?
2
Is
pi
rational or irrational?
Irrational - it's decimal goes on forever without repeating.
3m + 6m - 2m = -49
Combine like terms
Divide by 7
m = -7
-2(d + 5) =14 - 5d
Distribute
Combine like terms & solve
d = 8
1/2 (-4d + 12) < 16
d > -5
