Question

Find the value of z.
z+6.1=0.5(z-0.4)/0.35-0.6(z-2.71)/0.42​

Answer 1

Answer:

z= -2.22

Step-by-step explanation:

$z+6.1=0.5(z-0.4)/0.35-0.6(z-2.71)/0.42​\\z+6.1=\frac{0.5(z-0.4)(6)-0.6(z-2.71)(5)}{2.1} \\2.1(z+6.1)=3(z-0.4)-3(z-2.71)\\2.1z+12.81=3z-1.2-3z+8.13\\2.1z=8.13-12.81\\z=\frac{-4.68x}{2.1} \\z= -2.22$

Answer 2

Answer:

(0.5/0.35)(x – 0.4) – (0.6/0.42)(x – 2.71) = x + 6.1 (x – 0.4)/0.7 – (x – 2.71)/0.7 = x + 6.1 (x – 0.4 – x + 2.71)/0.7 = x + 6.1 -0.4 + 2.71 = 0.7(x + 6.1) 0.7x = 2.71 – 0.4 – 4.27 = -1.96 x = -1.96/0.7 = -2.8Read more on Sarthaks.com - https://www.sarthaks.com/664948/solve-the-equationand-also-check-your-results-0-5-x-0-4-0-35-0-6-x-2-71-0-42-x-6-1
