Question

: Solve 2.4x + 1.35 – 0.04x = 3.71x + 13.5
4​

Answer 1

Answer:

(2.4 -0.04-3.71)x +1.35=13.5

-1.35x+1.35=13.5

1.35(1-x)=13.5

x=1-10 =9

Answer 2

Answer:

-9

2.4x+1.35-0.04x=3.71x+13.5

We move all terms to the left:

2.4x+1.35-0.04x-(3.71x+13.5)=0

We add all the numbers together, and all the variables

2.36x-(3.71x+13.5)+1.35=0

We get rid of parentheses

2.36x-3.71x-13.5+1.35=0

We add all the numbers together, and all the variables

-1.35x-12.15=0

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

-1.35x=12.15

x=12.15/-1.35

x=-9
