3(2x + 1) for = x8 help me please

x=1.5 assuming the equation was 3(2x+1)=8x and x8 was a typo. This is because when u distribute the 3 into the parenthesis to get 6x+3 you then isolate the variables and the constants on one side by subtracting 6x from both sides. This will result in 3=2x and this devided is x=1/5

2.   2 3/5.

3.   2 1/2.

step-by-step explanation:

6 - 3 2/5

= 6 -   17/5

= 30/5 - 17/5

= 13/5

= 2 3/5 (answer).

5 1/4 - 2 3/4

= 21/4 - 11/4

= 10/4

= 2 1/2 (answer).
