Yep that's right.
thanks
can you solve those together? there are a few techniques for this.
let me see
20=55-3x
75=-3x
not quite. to get rid of the x on the left, subtract x to both sides. -4x - (1)x = -5x
same with the 55.
75=-5x
what about: 25 - 55 = ?
isn't 20
subtract 55
it's a negative number.
?????????
20 - 55 = -35
you have to subtract 55 from both sides.
where did you get -35
20 - 55 = 20 + -55 = -55 + 20 = -35
-35=-5x
that's right.
x=7
