[07]Multiplying both sides by 100,we get
100+100x=175-175x
100x+175x=175-100
275x=75
x=75/275= 3/11

Add 1.75X - 1 to each side of the equation and you get 2.75 X = 0.75.
X = 0.75/2.75 = 0.2727...
X = 0.75/2.75 = 0.2727...

1.00 + X=1.75 - 1.75X (Start with the equation)
X=1.75 - 1.75X - 1.00 (Transpose 1.00 to the right side)
1.75X + X = 1.75 - 1.00 (Transpose 1.75 to the right side)
2.75X = 0.75 (Simplify the equation)
X = 0.75 / 2.75 (Divide 2.75 to both sides to isolate X)
X = 0.27272727272727...
OR
X = 3 / 11
X=1.75 - 1.75X - 1.00 (Transpose 1.00 to the right side)
1.75X + X = 1.75 - 1.00 (Transpose 1.75 to the right side)
2.75X = 0.75 (Simplify the equation)
X = 0.75 / 2.75 (Divide 2.75 to both sides to isolate X)
X = 0.27272727272727...
OR
X = 3 / 11

1.00+x=1.75-1.75x
1.00 + x +1.75x = 1.75 - 1.75x + 1.75x (add 1.75x to both sides)
1.00 +2.75x = 1.75
1.00 - 1.00 +2.75x = 1.75 - 1.00 (subtract 1.00 from both sides)
2.75x = 0.75
2.75x/2.75 = 0.75/2.75 (divide both sides by 2.75)
x = .27 repeating (or, the fraction 3/11 is a nicer and better answer)
1.00 + x +1.75x = 1.75 - 1.75x + 1.75x (add 1.75x to both sides)
1.00 +2.75x = 1.75
1.00 - 1.00 +2.75x = 1.75 - 1.00 (subtract 1.00 from both sides)
2.75x = 0.75
2.75x/2.75 = 0.75/2.75 (divide both sides by 2.75)
x = .27 repeating (or, the fraction 3/11 is a nicer and better answer)

1.00+X=1.75-1.75x
multiply both sides by 4
4 + 4x = 7 - 7x
combine similar terms
4x + 7x = 7 - 4
11x = 3
x = 3/11
multiply both sides by 4
4 + 4x = 7 - 7x
combine similar terms
4x + 7x = 7 - 4
11x = 3
x = 3/11

1.00+x=1.75-1.75x
x+1.75x=1.75-1.00
2.75x=0.75
x=0.75/2.75
=0.2727
x+1.75x=1.75-1.00
2.75x=0.75
x=0.75/2.75
=0.2727

are both the Xs the same variable? if they are...then
isolate x's on one side and isolate the numbers on the other
then divide both sides by the x coefficient
and you find what x is equal to
isolate x's on one side and isolate the numbers on the other
then divide both sides by the x coefficient
and you find what x is equal to

Subtract both sides by 1.00
1.00-1.00+x=1.75-1.00-1.75x
Substitute
1x=0.75-1.75x
Add both sides by 1.75x
1x+1.75x=0.75-1.75x+1.75x
Substitute
2.75x=0.75
Divide both sides by 2.75
2.75x/2.75=0.75/2.75
Solve for x
x= 0.272
1.00-1.00+x=1.75-1.00-1.75x
Substitute
1x=0.75-1.75x
Add both sides by 1.75x
1x+1.75x=0.75-1.75x+1.75x
Substitute
2.75x=0.75
Divide both sides by 2.75
2.75x/2.75=0.75/2.75
Solve for x
x= 0.272
