Which equation is correct regarding the measure of 21?
m_1 = 1 (a -c)
m21 = (a + c)
o mz1 = {(0-0)
o mz1 = (b + 0)

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?
