Hey I need you guys' help

This is about circle theorems. someone asap : (

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?

Complete the conditional statement. if a + 2 < b + 3, then a < b b < a a – b < 1 a < b + 1
