0.6x-1.8=1.2x
collect like terms
0.6x-1.2x=1.8
-0.6x=1.8
make x the subject of the formula
x=1.8/-0.6
x=-3
Subtract 0.6x from both sides:
-1.8 = 0.6x
Divide both sides by 0.6:
-3 = x
0.6x-1.8 = 1.2x subtract 0.6x from both sides
-1.8 = 0.6x divide both sides by 0.6
-3 = x
Get rid of the decimals as often as you can.
Multiply throughout by 10
This will give you
6x-18=12x
arranging like terms gives you
12x-6x = -18
6x=-18
x=-18/6 = -3
How do you solve this and whats the answer thanks
