show all steps
To combine like terms and simplify the expression −3(−4y+3)+7y, we first distribute the −3 to the terms inside the parentheses:
−3 × −4y + (−3 × 3) + 7y
This becomes:
12y − 9 + 7y
Next, we can combine the like terms 12y and 7y:
12y + 7y − 9
Finally, we can add the coefficients of the y terms:
19y − 9
So, the simpler form of the expression −3(−4y+3)+7y is 19y − 9.
