Answer:
19y-9
Step-by-step explanation:
apply distributive property
-3(-4y)-3 x 3 + 7y
12y - 3 x 3 + 7y
12y - 9 + 7y
add 12y to 7y
19y-9
-3(-4y + 3) + 7y Distribute -3 into (-4y + 3)
(-3)(-4y) + (-3)3 + 7y (two negative signs cancel each other out and become positive)
12y - 9 + 7y Combine like terms(terms that have the same variable and power/exponent), which are only 12y and 7y because the have the same variable of y and an exponent of 1
19y - 9 (this is as far as you can simplify)
