Respuesta :
1. subtract y from both sides 3y-4=y+10
. -3 -3
2.now you have -4=-2y+10 subtract 10 to both sides
-10 -10
3. you have -14=-2y divide
4. y=7
. -3 -3
2.now you have -4=-2y+10 subtract 10 to both sides
-10 -10
3. you have -14=-2y divide
4. y=7
Answer: the correct option is
(d) 7.
Step-by-step explanation: We are given to solve the following open sentence :
[tex]3y-4=y+10~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To solve the given equation, we need to find the value of the unknown variable y.
The solution of equation (i) is as follows :
[tex]3y-4=y+10\\\\\Rightarrow 3y-y=10+4\\\\\Rightarrow 2y=14\\\\\Rightarrow y=\dfrac{14}{2}\\\\\Rightarrow y=7.[/tex]
Thus, the required solution is y = 7.
Option (d) is CORRECT.
