Can you guys distribute 7(4y+5)=19y+8 and figure out how many solutions this problem has plz and thank you

Alik [6]

It should only have one solution.
After distributing, you have the equation
$28y + 35 = 19y + 8$
Subtract applicable things.
$9y = -27$
divide both sides by 9.
$y = -3$

therefore the solution is
$y = -3$
