Answer 1

Hello There!!

Solution For Given Question

Three times x is 13 less than y

$3x = y - 13 \\ = > 3x + 13 = y$

The sum of x and two times y is 12.

$x + 2y = 12$

Replacing Value of Y with 3x + 13

$x + 2y = 12 \\ \\ \implies x + 2(3x + 13) = 12 \\ \\ \implies x + 6x + 26 = 12 \\ \\ \implies7x = 12 - 26 \\ \\ \implies 7x = - 14 \\ \\ \implies x = \cancel\frac{ - 14}{7} \\ \\ \implies x = - 2$

Now we need to fine Value of'y' i e.,

$y = 3x + 13 \\ \\ \implies y = 3( - 2) + 13 \\ \\ \implies y = - 6 + 13 \\ \\ \implies y = 7$

$\therefore \text{option c.(y = 7) is your answer}$

Hope this helps
