Answer:


Step-by-step explanation:

1) Write 8x+14 as 2(4x+7) and now multiply by 1/2 so that we get 4x+7

2)Subtract 7 from both sides

4x+7=39

-7       -7

4x=32

3) Divide by 8

x=8

Thus we get x=8 as answer

So reasons are

i) Distributive property

ii) Subtraction property of equality

iii) Division property of equality

Answer: x = 8

Step-by-step explanation:

1/2(8x+14) = 39 (given)

4x + 7 = 39 (open the bracket)

4x = 39 -7 (collect like term)

4x = 32 (divide bothside by 4)

4x/4 = 32/4

x=8
