Answer
25.67 x 10 square root -2 ..........<span>is NOT written in scientific notation
should be
</span>2.567 x 10 square root -3 (in scientific notation form)
8-5y= -2x
⇒ -5y= -2x-8
⇒ y= -2/(-5)x -8/(-5)
⇒ y= 2/5x+ 8/5
The final answer is y= 2/5x+ 8/5~
(5x) / (2/11) = 3 / (1/5)
cross multiply
(5x)(1/5) = (2/11)(3)
x = 6/11
