What is the value of 1/3× + 7x, when x =5

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.

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?
