Answer:
no solution
Step-by-step explanation:
Given
2(x + 1) = 2x + 5 ← distribute parenthesis on left side
2x + 1 = 2x + 5 ( subtract 1 from both sides )
2x = 2x + 4 ( subtract 2x from both sides )
0 = 4 ← not possible
This indicates the equation has no solution

Answer:
Step-by-step explanation:
1) Each of the ratios can be reduced to 1 : 5, Since both can be reduced to the same ratio, the do form a proportion.
4 : 20 = 1 : 5
6 : 30 = 1 : 5
__
2) The first ratio can be reduced to 1/2. The second ratio is not 1/2 and cannot be reduced. Since they are different ratios, they do not form a proportion.
9/18 = 1/2
3/8 = 3/8
