Since −15=9 is not true, there is no solution.
Let's solve the system of equations using substitution.
Given:
y=4x+5 ...(Equation 1)
12x−3y=9 ...(Equation 2)
We can start by substituting Equation 1 into Equation 2 to solve for x:
From Equation 1:
y=4x+5
Now, replace y in Equation 2 with 4x+5:
12x−3(4x+5)=9
Simplify the equation:
12x−12x−15=9
−15=9
Since −15=9 is not true, there is no solution.
