Question

12y+d=−19y+t Solve for y

Answer 1

Hi!

Solve for d.

$12y+d=-19y+t$

Subtract by 12y from both sides.

$12y+d-12y=-19y+t-12y$

$Answer---> d=-31y+t$

Solve for y.

Add 19y from both sides.

$d+12y+19y=t-19y+19y$

$d+31y=t$

Add d from both sides

$d+31y+-d=t+-d$

$31y=-d+t$

Divide by 31 from both sides.

$\frac{31y}{31}=\frac{-d+t}{31}$

$Answer ----> y=\frac{-1}{31} d+\frac{1}{31}t$

Hope this helps!
