Answer:
Step-by-step explanation:
Cross multiply the givens
3b = 4a Divide both sides by 4
3b/4 = a Now divide by b
3/4 = a/b
This can be written as
3:4 :: a:b
2800=400.21x
x = 6.996327
Answer: The approximate solution is (-0.36, 2.08).
Given system of equations : x+5y=10 and 3x+y=1
7/2
x = 15
-x = -15
x = -1 × (-15)
<u>x</u><u> </u><u>=</u><u> </u><u>1</u><u>5</u>
