Question

Solve the system of equations using the addition/subtraction method.

Answer 1

4x + 2y = 22
3x + 4y = 24
Use the process of elimination. Where you can either decide which number variation you want to eliminate by multiplying it with a negative or positive, then distribute it on your chosen equation.
- 2 X (4x + 2y = 22)- - > - 8x - 4y = - 44
- 8x - 4y= - 44
3x + 4y= 24
- 4y and +4y will cancel out by means of canceling y and you are left solving for x.
- 5x = - 20
Divide - 5 on both sides.
x= 4
3 X (4) + 4y=24
Plug your 4 to the x of 3 and multiply. Now you will be solving for y.
12 + 4y=24
4y = 24 - 12
y= 3
Final answer: (4,3)
