Question

Can anyone help me with this two-step equation:

10=0.3x-9.1

Answer 1

we are solving for x. To get x alone, we need to isolate the term with x only to one side of the equation. In this case, let's isolate the term with x (which is 0.3x) on the right side, thus we will transpose the -9.1 on the left side. To do this, the its sign must be opposite (becomes +9.1):
10 = 0.3x - 9.1
10 + 9.1 = 0.3x
19.1 = 0.3x
finally, we divide both sides of equation by 0.3 to get x alone:
19.1/0.3 = (0.3x)/0.3
63.67 = x, or
x = 63.67

hope this helps~ :)
