1.4=x(1.2)+(1-x)(1.8)

Solution for 1.4=x(1.2)+(1-x)(1.8) equation:

1.4=x(1.2)+(1-x)(1.8)

We move all terms to the left:

1.4-(x(1.2)+(1-x)(1.8))=0

We add all the numbers together, and all the variables

-(x(1.2)+(-1x+1)(1.8))+1.4=0

We multiply parentheses ..

-(x(1.2)+(-1.8x+1.8))+1.4=0


We calculate terms in parentheses: -(x(1.2)+(-1.8x+1.8)), so:

x(1.2)+(-1.8x+1.8)

We multiply parentheses

1.2x+(-1.8x+1.8)

We get rid of parentheses

1.2x-1.8x+1.8

We add all the numbers together, and all the variables

-0.6x+1.8

Back to the equation:

-(-0.6x+1.8)


We get rid of parentheses

0.6x-1.8+1.4=0

We add all the numbers together, and all the variables

0.6x-0.4=0

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

0.6x=0.4

x=0.4/0.6

x=0.4/0.6
