Question

48y + 41y + 34y + 13x + 34y

Explanation:

Step1: Group like terms

Group all $y$-terms and the $x$-term separately:
$(48y + 41y + 34y + 34y) + 13x$

Step2: Combine $y$-terms

Calculate the sum of the $y$-coefficients:
$48 + 41 + 34 + 34 = 157$, so the $y$-terms simplify to $157y$

Step3: Write simplified expression

Combine the simplified terms:
$13x + 157y$

Answer:

$13x + 157y$
