80 - 2p
You use the distributive property
Y=4x i believe is the answer
6x+8x+40=180
14x = 140
x = 10
7y + 3y - 10 = 180
10y = 190
y = 19
A coefficient is the number that is multiplied by the variable (the letter).
so the coefficient in ur expression is 3.
the 2 and the 4 are constants...because they are numbers with no variables
