Solve the system of linear equations by substitution. y-x=0 2x-5y=9

Select all the equations for which 9 is a solution. x+8=1 7+x=16 x-8=1 x-7=-16

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 =
