Decided weather or not n=9 is a solution to the equation 2+n=7.

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?

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?
