Answer:
3x - 3
Step-by-step explanation:
(x + 4) + (2x - 7) =
The first step is to drop the parentheses since they are unnecessary.
= x + 4 + 2x - 7
Now group like terms together.
= x + 2x + 4 - 7
Combine like terms.
= 3x - 3
Answer:
4 1/6
Step-by-step explanation:
Set up the division problem in long division format.
6/25
Divide
25 by 6
<span>Simplifying
2d + -5 = 17
Reorder the terms:
-5 + 2d = 17
Solving
-5 + 2d = 17
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + 5 + 2d = 17 + 5
Combine like terms: -5 + 5 = 0
0 + 2d = 17 + 5
2d = 17 + 5
Combine like terms: 17 + 5 = 22
2d = 22
Divide each side by '2'.
d = 11
Simplifying
d = 11 </span>
