90 + .65x = .55(200x)

90 + .65x = 110x

90 + .65x - .65x = 110x - .65x

90 = 109.35x

90 / 109.35 = 109.35x / 109.35

90 / 109.35 = x

0.823045267 = x

90 +.65x=.55(200x)
*multiply .55 by 200x
90+.65x=110x
*your goal is have the variable on the same side so you are going to subtract the .65x from both sides.
90=109.35x
*Now you are going to divide both sides by 109.35 to isolate the variable x therefore it can be solved.
x=0.8230452
*You may wish to round the final product or leave it as is, depending on how the problem is asking you to answer the question.

These are 2 different equations

90 + .65x = .55(200x)
90+.65x=110x subtract .65x from each side
90=109.35x divide both sides by 109.35
x=90/109.35=0.823

or

90 .65 = .55(200x)
90.64=110x divide by 110
x=90.65/110=0.824

90 + .65x = .55(200x)

First: multiply .55 with 200x ...

90 + .65x = 110x

Sec: subtract .65x from both sides (opposite side means opposite sign) ...

90 + .65x - .65x = 110x - .65x
90 = 109.35x

Third: solve for "x" by isolating it on one side > divide both sides by 109.35 ...

90/109.35 = 109.35x/109.35
.82 = x
x = .82

90 + .65x = .55(200x)?
90 = .55(200x) - .65x
90 = 110x-.65x = 109.35x
90/109.35 = 0.8230453 = x

90+.65x=110x

Subtract .65x from both sides:
109.35x=90

Divide 109.35 from both sides:
x=90/109.35=0.823

90+.65x=110x
90=109.35x
x=90/109.35
x=.82

90+.65x=110x
90=109.35x
x=109.35/90
And there you have it
