Question
4x + y = 4 &
8x + y = 5
If (x, y) is the solution of the system of equations above, what is the value of x?
The correct answer is: 0.2
Linear equations to be solved simultaneously to find the value of x
Step-by-step solution:-
4x + y = 4 ____________ (Equation i)
8x + y = 5 ______________ (Equation ii)
Subtracting equation i from ii,
8x + y = 5
- 4x + y = 4
(-) (-) (-)
4x + 0 = 1
∴ 4x = 1
x = 0.2
Final Answer:-
∴ For the given Linear equations, value of x = 0.2
