Question

Find the value of 3y-4 given 2y-6=8Simplify your answer as much as possible 3y-4=

Answer 1

Answer:

3y-4= 17

Explanation:

First, we have to find the value of y from 2y - 6 = 8.

Adding 6 to both sides gives

$2y=8+6$$\Rightarrow2y=14$

dividing both sides by 2 gives

$\frac{2y}{2}=\frac{14}{2}$$\Rightarrow\boxed{y=7.}$

With the value of y in hand, we can now evaluate 3y - 4.

Putting in y = 7 into 3y - 4 gives

$3(7)-4=17$

Hence,

$\boxed{3y-4=17.}$
