Answer:
The solution is x=-6 and y=7
Step-by-step explanation:
Given equations are:
In elimination method, the co-efficient of one of the variables are equated so that one variable can be eliminated by adding or subtracting the equations
In the given system of equations, the co-efficient of y is already same i.e. 4 so we only have to subtract the equations
Subtracting equation 2 from equation 1
Putting x = -6 in equation 1
Hence
The solution is x=-6 and y=7
Answer: 16
Step-by-step explanation:
multiply 6 by the answers below until you get 1/3 of 384.
Answer:
Step-by-step explanation:
Isolate the b from one side of the equation.
<u>First, subtract by 5 from both sides.</u>
<u>Solve.</u>
<u />
<u>Subtract.</u>
9-5=4
2b=4
<u>Divide by 2 from both sides.</u>
2b/2=4/2
<u>Solve.</u>
<u />
<u>Divide the numbers from left to right.</u>
4/2=2
Therefore, the correct answer is b=2.
I hope this helps, let me know if you have any questions.
Up where is the picture for this to see the other angles<span />
48.6 is 200% of 24.3
Divide:
48.6 / 24.3 = 2
Change to percentage:
2 × 100 = 200
