Question

.Solve the following:

((3x – 8)/2x) = 1

(5x/(2x – 1)) = 2

((2x – 3)/(4x + 5)) = (1/3)

[(5(1 – x)) + (3(1 + x))/ (1 – 2x)] = 8

[(y – (4 – 3y))/ (2y – (3 + 4y))] = 1/5

10x – 5 – 7x = 5x + 15 – 8

5(x – 1) – 2(x + 8) = 0

4t – 3 – (3t +1) = 5t – 4​

Answer 1

Answer:

Although hydrogen has the highest calorific value, it is not used as a domestic fuel. It is because hydrogen is a highly combustible and it reacts explosively when it comes in contact with air. ... So, even though hydrogen has the highest calorific value, it is not used as a domestic fuel.

Answer 2

Answer:

4t - 3 - (3t +1) = 5t - 4

4t - 3 - 3t - 1 = 5t - 4

1t - 4 = 5t - 4

1t - 5t = -4 -4

-4t = - 8

t = -8 / -4

t= 2
