Answer:
Step-by-step explanation:
Let's multiply the first equation by 7 and the second equation by -2
Now add them together. In this step, x is eliminated.
Divide by 26.
Now plug this into any of the two equations to find x.
what I put into my basic calculator is 5(3/4)-6(1/8)= 3 ft
5x + 14 = k
Subtract 14 from both sides.
5x = k - 14
Divide both sides by 5.
x = k/5 - 14/5
So, your answer is B

X + Y = 10
X + 2Y = 16
First, subtract Y from both sides in X + Y = 10.
X = 10 - Y
X + 2Y = 16
Next, plug X into X + 2Y = 16.
X = 10 - Y
10 - Y + 2Y = 16
Afterwards, simplify.
X = 10 - Y
Y + 10 = 16
Subtract 10 from both sides in Y + 10 = 16
X = 10 - Y
Y = 6
Finally, plug Y into X = 10 - Y
X = 10 - 6
Y = 6
Simplify
X = 4
Y = 6
