Question

2. Find the value of b if (-3.4) is a solution of the equation 3x-4y=5b. Hence find
other two solution of the equation​

Answer 1

3x-4y=5b

substituting x=-3 and y=4

3(-3)-4(4)=5b

-9-16=5b

-25=5b

b=-25/5

b=-5

this is your solution

Answer 2

Step-by-step explanation:

Given equation :

3x - 4y = 5b

Where,

x = (-3)

y = 4

Substitution of the given values :

$\sf : \implies \: 3x - 4y = 5b \\ \sf : \implies \: 3( - 3) - 4(4) = 5b \\ \sf : \implies \: - 9 - 16 = 5b \\ \sf : \implies \: - 25 = 5b \\ \sf : \implies \: b = \frac{ - 25}{5} \\ \sf : \implies \: b = - 5 \: ans.$
