Problem |
Solve the equation \$ (6y - 4)/2 = (3y + 1)/4 \$. |
|
2 |
Step |
The given equation |
\$ (6y - 4)/2 = (3y + 1)/4 \$ |
3 |
Step |
Start by multiplying both sides of the equation by the LCM of the denominators, which is 8: |
\$8 times ( (6y - 4)/2) = 8 times ((3y + 1)/4) \$ |
4 |
Step |
After simplification |
4(6y - 4) = 2(3y + 1) |
5 |
Step |
Expanding both sides: |
24y - 16 = 6y + 2 |
6 |
Step |
To isolate the variable terms on one side, let’s subtract 6y from both sides: |
24y - 16 - 6y = 6y + 2 - 6y 18y - 16 = 2 |
7 |
Step |
Add 16 to both sides: |
18y - 16 + 16 = 2 + 16 18y = 18 |
8 |
Step |
Finally, to solve for y, divide both sides by 18: |
\$ 18/18 y = 18/18 \$ |
9 |
Solution |
After simplification we get y = 1 |

Choice-A |
The equation does not have any solutions where y = 0, so this is not correct |
Wrong 0 |
12 |
Choice-B |
This is correct because the y value satisfies the given equation |
Correct 1 |
13 |
Choice-C |
The equation does not have any solutions where y = - 1, so this is not correct |
Wrong -1 |
14 |
