Question

Solve the following equations and check your
answers :
(i) 0.3 t +0.2 = 0.4 t +0.5​

Answer 1

Answer:

0.3t+0.2=0.4t+0.5

We move all terms to the left:

0.3t+0.2-(0.4t+0.5)=0

We get rid of parentheses

0.3t-0.4t-0.5+0.2=0

We add all the numbers together, and all the variables

-0.1t-0.3=0

We move all terms containing t to the left, all other terms to the right

-0.1t=0.3

t=0.3/-0.1

t=-2+0.1/0.1

Answer 2

Answer:

0.3t+0.2=0.4t+0.5

We move all terms to the left:

0.3t+0.2-(0.4t+0.5)=0

We get rid of parentheses

0.3t-0.4t-0.5+0.2=0

We add all the numbers together, and all the variables

-0.1t-0.3=0

We move all terms containing t to the left, all other terms to the right

-0.1t=0.3

t=0.3/-0.1

t=-2+0.1/0.1
