Answer 2

Answer:

y=2

*The answer must have a positive sign.*

Step-by-step explanation:

First, add by 1 from both sides of an equation.

$3y-1+1=13-4y+1$

Then, simplify by equation.

$3y=-4y+14$

Next, add by 4y from both sides of an equation.

$3y+4y=-4y+14+4y$

Simplify.

$7y=14$

Divide by 7 from both sides of an equation.

$\frac{7y}{7}=\frac{14}{7}$

And finally, simplify by equation.

$14/7=2$

$14/2=7$

$2*7=14$

$7*2=14$

Answer: → $y=2$
