Can someone help me with this? Thanks! ;)

Steve had 48 chocolates but decided to give 8 chocolates to each of his ff coworkers. how many chocolates does steve have left? write your answer as an expression.

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
