Good afternoon to anyone that reads this in plz click on my user click thanks and plz tell me any questions u like Just a few thing you need to know when u ask me questions I am in 5th grade and I am a expert in e. l.a and science

3x + 4y = 5 x- 3y = -7 solve by substitution

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?

Either enter an exact answer in terms of \piπ or use 3.143.14 for \piπ and enter your answer as a decimal.
