Reply With QuoteAre you sure you typed that correctly? Might the problem read:
1.7x +8 -1.62x + 0.4x =7.68 Solve for X????
If so, combine all the X variable items and set them equal to 7.68-8...
1.7x +8 -1.62x = 0.4x +7.68 Solve for X.
Steps would be nice....7th grade math....
My mistake, the + and the = are on the same key..does that help. I've been doing alright helping out till we got to this one

You have too many = signs re check the problem
1.7x +8 -1.62x = 0.4x +7.68 Solve for X.

fixed.
X=1.
All of the items on the left with an x can be added together, 1.7-1.62=.08X
Now we have .08X+8=.4X+7.68
Now isolate the X's by subtracting .08X from both sides.
do this and you will have 8= .32X+7.68.
Subtract 7.68 from both sides and you have .32=.32X.
Test it out by placing a 1 in place of the X's in the original equation.
Do whatever you have to do in order to get your e"X" by herself..
1.7x +8 -1.62x = 0.4x +7.68 Solve for X.
1.7x -8 +8 -1.62x = .4x + 7.68 - 8
Whatever you do to one side of = you have to do to the other in order so isolate x
you now have
1.7x-1.62x = .4x + -.32
1.7x-1.62x-.4x= .4x-.4x-.32
1.7x-1.62x-.4x= -.32
-.32x= 1.68
-.32x/-.32=-.32/.-32
x= 1
or somethinglike that...lol

So x = 1 ? that would be tricky of them

Nice Edit, poolboy.....
1.7x +8 -1.62x = 0.4x +7.68 Solve for X.
Steps would be nice....7th grade math....

1.7x +8 -1.62x = .4x +7.68
1.7x -1.62x -.4x = 7.68 - 8
.32x = .32
.32x = .32
.32 = .32
1x= 1
or x = 1
Roz, drinking and math don't mix
