Answer:
Step-by-step explanation:
To solve this problem, you have to combine like terms of x and b from one side of the equation.
<h3>4x+3(2x+5b)-4b-2x+6</h3>
<u>Combine like terms.</u>
3(2x+5b)+4x-2x-4b+6
<u>Solve.</u>
4x-2x=2x
Rewrite the problem down.
3(2x+5b)+2x-4b+6
Expand the form.
Use a distributive property.
<u>Distributive property:</u>
A(B+C)=AB+AC
3(2x+5b)
<u>Multiply.</u>
3*2x=6x
3*5b=15b
<u>Rewrite the problem.</u>
6x+15b
6x+15b+2x-4b+6
<u>Combine like terms.</u>
6x+2x+15b-4b+6
<u>Add the numbers from left to right.</u>
6x+2x=8x
8x+15b-4b+6
<u>Then, you add again.</u>
15b-4b=11b
<u>= 8x+11b+6</u>
- <u>Therefore, the final answer is 8x+11b+6.</u>

Answer:
1. x = 86
2. x = 31
3. x = 64
4. x = 29
Step-by-step explanation:
1. 2x + 8 = 180
-8 -8
2x = 180 (divide both sides by 2 to get x by itself)
2. 3x - 3 = 90
+ 3 +3
3x = 93 (divide both sides by 3 to get x by itself. you divide because 3x is multiplying and you have to do the reverse operation)
3. 2x -5 + x - 7 = 180 (you combine like-terms)
3x -12 = 180
+12 +12
3x = 192 (you divide by 3 on both sides)
4. x + 1 + x + 4 + x - 2 = 90 (combine like-terms)
3x + 3 = 90
-3 -3
3x = 87 (divide both sides by 3)
Answer:
B. 7(6x – 1) and 42x – 7 is equivalent
Step-by-step explanation:
A. –3(3x + 5) and –9x + 5
=–3(3x + 5)=-9x-15 not equivalent
B. 7(6x – 1) and 42x – 7
7(6x – 1)=42x-7 equivalent
C. –6(4x – 3) and –6x
=–6(4x – 3)=-24+18 not equivalent
D. 5(2x + 3y) and 25xy
=5(2x + 3y)=10x+15y not equivalent.
