Subtract -7x-9 from -4x^2+3x-5

16 more than the product of 5 and p

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?

Plzzz answer both questions and i will give you 100 points
