I need value of x and rs please

x=5

RS=6

Step-by-step explanation:

to find RS you should follow this equation,

4x-4 = 5x-9

4x-5x= -9+4

-x = -5

-x/-1= -5/-1

x=5

then RS,

=5x-9

=5×5-9

=15-9

=6

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
