Question

Solve the equation: 3(2y-5)=9 for y

Answer 1

$3\cdot(2y-5)=9$

Applying the distributive property in this case:

$6y-15=9$

Adding 15 at both sides of the equation:

$6y-15+15=9+15\rightarrow6y+0=24$

Then

$6y=24$

Dividing both sides by 6, we finally have:

$\frac{6}{6}y=\frac{24}{6}\rightarrow y=4$

Therefore, the value for y = 4.
