=> 0.3(6+t) = 0.4(8-t) no spam..

Step-by-step explanation:

t = 2

Step-by-step explanation:

0.3( 6 + t) = 0.4(8 - t)

Distribute 0.3 in Left hand side and 0.4 in right hand side.

0.3 × 6 + 0.3 × t = 0.4 × 8 - 0.4 × t

1.8 + 0.3t = 3.2 - 0.4t

Move 0.3t to the Right hand side and change their sign.

1.8 = 3.2 - 0.4t - 0.3t

1.8 = 3.2 - 0.7t

Move 3.2 to the left hand side and change their sign.

1.8 - 3.2 = - 0.7t

-1.4 = -7t

Divide both side by -7.

-1. 4 / -7 = -7t / -7

2 = t
