Hello,

Ali is right, Khamis is wrong. Why because Khamis forgot to put the negative sign in front of 5b, it should be wrote -5b in the second line and not 5b.

And then Khamis should have divided -5b by -5b.

Good Luck

Negative 4.2x+31.5=negative 65.1
Rasek [7]
It is a linear simple equation for one unknown, lets solve it!
-4.2x + 31.5 = -65.1
we can easily get rid of decimals if we multiply the whole equation times 10:
<span>-42x + 315 = -651
</span>-42x = -651 - 315 = -966
x = 966/42
x = 23
that is the solution
