Question

Determine the solution of the equations a-b=1.1 and 12(a+b)power-1=5

Answer 1

Answer:

a = 1.75, b = 0.65

Step-by-step explanation:

Given equations

$a-b=1.1$   ............. (1)

$12(a+b)^{-1}=5$

$\implies \frac{12}{a+b}=5$

$\implies {a+b}=\frac{12}{5}$

$\implies {a+b}=2.4$    .......... (2)

Adding eq (1) and (2)

$2a=3.5$

$\implies a=\frac{3.6}{2}$

or, $a=1.75$

Putting the value of a in eq (2)

$1.75 + b=2.4$

$\implies b=2.4-1.75$

$b=0.65$

Thus,

a = 1.75, 0.65

I hope this answer is helpful to you.
