What is the value of y if (4y + 8) - (7t - 12) = 11?

If the '7t' is supposed to be '7y', then the answer is below

(4y+8) - (7y-12) = 11

distribute the negative into the second parenthesis

4y+8-7y+12=11

combine like terms

-3y+20=11

subtract the 20 from both sides

-3y=-9

divide by - 3 on both sides

y=3

if it is supposed to be '7t', I'm not sure if there's enough information
