Answer: 2.4
Step-by-step explanation:
The value of x from the system of equation is 0
Given the systems of equation
–3x + 8y = 16
3x + 4y = 8
Using the elimination method.
Add both equations
-3x + 3x + 8y + 4y = 16 + 8
12y = 24
y = 24/12
y = 2
Substitute y = 2 into equation 2:
3x + 4y = 8
3x + 4(2) = 8
3x = 8 - 8
3x = 0
x = 0
Hence the value of x from the system of equation is 0.
