2x + 4y = 12 y = A system of equations. 2 x plus 4 y equals 12. y equals StartFraction one-fourth EndFraction x minus 3.x – 3 What is the solution to the system of equations?
Answers
Answer:
From the system of equation 2x + 4y = 12 and y equals StartFraction one-fourth EndFraction x minus 3. The solution to the system of equations in terms of (x, y) is equal to ( (8, -1)
The system of equations is given as:
2x + 4y = 12 ------- (1)
\mathbf{y = \dfrac{1}{4}x - 3} \ \ \ ----(2)y=

x−3 −−−−(2)
So, from equation (1), we will replace the value of y which is \mathbf{ \dfrac{1}{4}x - 3} } in order to be able to solve for x.
i.e.
\mathbf{2x + 4\Big ( \dfrac{1}{4}x -3 \Big) = 12 }2x+4(

x−3)=12
Open brackets
2x + x -12 = 12
3x - 12 = 12
3x = 12 + 12
3x = 24
x = 24/3
x = 8
Now, we will replace the value of x into equation (2) to be able to solve for y.
\mathbf{y = \dfrac{1}{4}(8) - 3} }
y = 2 -3
y = -1
Therefore, the solution to the system of equations in terms of (x, y) is equal to ( (8, -1)
