Can anyone answer this question please<br> 6[y-2]/7-12=2[y-7]/3
Kaylis [27]

Answer:

y =47.5.

Step-by-step explanation:

First eliminate the fractions by multiplying through by the LCM of 7 and 3 which is 21:

21* 6[y-2]/7-21*12 = 21*2[y-7]/3

18(y - 2) - 252 = 14(y - 7)

18y -36 - 252 = 14y - 98

18y - 14y = -98 + 36 + 252

4y = 190

y = 190/4

y = 47.5.

What is the solution of log (t minus 3) = log (17 minus 4 t)?<br> 4<br> 5<br> 15<br> 20
Tcecarenko [31]

Option A: 4 is the solution

Explanation:

The given expression is \log (t-3)=\log (17-4 t)

We need to determine the solution of the expression.

<u>Solution:</u>

The solution of the expression can be determined by solving the expression for t.

Let us solve the given expression.

Applying the log rule, if \log _{b}(f(x))=\log _{b}(g(x)) then f(x)=g(x)

Thus, we have;

t-3=17-4 t

Adding both sides of the equation by 4t, we get;

5t-3=17

Adding both sides of the equation by 3, we have;

5t=20

Dividing both sides of the equation by 5, we get;

t=4

Hence, the value of t is 4.

Therefore, the solution of the given expression is 4.

Thus, Option A is the correct answer.
