Question

0.15-2x=1.15

Answer 1

We like to have the variable by itself in the left side. There are various tricks to do this.

0.15-2x=1.15

put changes in the next line

always do the same thing to both sides of the equation

0.15-2x=1.15

subtract .15 from both sides

-2x=1.15 - .15

-2x = 1

multiply by-1

2x = -1

Divide by 2

X = - 1/2

Hope this helps

Answer 2

0.15-2x=1.15

-2x= 1.15-0.15

-2x=1

X= -1/2
