Question

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

Answer 1

Hello from MrBillDoesMath!

Answer: 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
