Y=3x-11 y-3x-13 solving system of equations by substitution

Hello from MrBillDoesMath!

 No (x,y) solution. Or solution set is the empty set

Discussion:

Assuming the equations are as follows:

y = 3x - 11

y = 3x - 13   (the original equation uses a "-", not "=" sign)

these lines are parallel (each has slope m = 3) and therefore have no points on intersection. The solution set is the empty set

Thank you,

MrB

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
