Answer:
B. 5+2(3+2x)=x+3(x+1)
Step-by-step explanation:
Expand the brackets.
5 + 6 + 4x = x + 3x + 3
11 + 4x = 4x + 3
Add -4x and -11 on both sides.
4x - 4x = 3 - 11
0 = -8
There are no solutions.

Step-by-step explanation:
Answers + Explanation:
1. x + 7 =10
if you know some number + 7 is 10, you know that number must be 3.
so, x = 3
the other way you can solve this would be:
x + 7 = 10
subtract 7 from both sides of the equation
x + 7 - 7 = 10 - 7
x = 3
2. Use the same strategy:
x - 8 = -5
add 8 to both sides of the equation
x - 8 + 8 = -5 + 8
x = 3
3. x + 3 = 6
subtract 3 from both sides of the equation
x + 3 - 3 = 6 - 3
x = 3
4. x + 6 = 3
subtract 6 from both sides of the equation
x + 6 - 6 = 3 - 6
x = -3
