Answer:
y= -3/2x + 5
Step-by-step explanation:
You do the opposite reciprocal of the original equation's slope.
Then you use the new slope from the point (4,-1) on the graph to find the y-intercept. Which is (0,5).
That gets your answer of -3/2x + 5.
The answer is 47/100 or it could also be 0.47
Answer:
x=5
Step-by-step explanation:
To start solving this, you want to solve an equation for y. I chose 3x - 7y = 4 for later purposes. Subtract 3x from both sides and divide by -7 to get y = 4 - 3x / -7. Now because we have a value for y in terms of x, plug this into the other equation, x + 7y = 16. It now should look like this: x + 7(4 - 3x / -7) = 16. Now just distribute the 7 and simplify the denominator to get x+ (-4+3x)=16. This can now be 4x +4 = 16, starting to look familiar now. Lastly subtract the 4 from both sides and divide by 4 to get x = 5. Hope this helps!
