Question

Help me please! So 2.35 + 0.25x = 1.75 + 0.40

Answer 1

x = -0.8

Explanation:

2.35+0.25x = 1.75+0.4

To find x, we must first isolate the value.

This is done by subtracting any values on the same side as the x.

Thus, we subtract 2.35 from both sides.

We are now left with the following:

0.25x=1.75+0.4-2.35

Now you should simplify the right side by finding the sum, which is -0.2, so:

0.25x=-0.2

Finally, solve by dividing each side by 0.25.

x = -0.8

Answer 2

`x = -(4)/(5) \ \ \textrm{or} \ \ x = -0.8`

Explanation:

First, multiply both sides by 100 to make the numbers nicer to work with.

`(100)(2.35 + 0.25x) = (1.75 + 0.40)(100)`

`235+25x=175+40`

Next, isolate x by moving all the constant terms to one side and then dividing by x's coefficient.

`25x=175+40-235`

`25x = -20\\\overline{\, \, 25 \, \,} \: \, \, \, \, \, \, \, \overline{ \,\, 25 \, \,}`

`x = -(20)/(25)`

`x = -(4)/(5)`

So, the value of x is -4/5 or 0.8.
