\frac{-23}{20}x-y=7
Expand \frac{-2.3}{2} by multiplying both numerator and the denominator by 10.
-\frac{23}{20}x-y=7
Fraction \frac{-23}{20} can be rewritten as -\frac{23}{20} by extracting the negative sign.
-\frac{23}{20}x=7+y
Add y to both sides.
-\frac{23}{20}x=y+7
The equation is in standard form.
\frac{-\frac{23}{20}x}{-\frac{23}{20}}=\frac{y+7}{-\frac{23}{20}}
Divide both sides of the equation by -\frac{23}{20}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y+7}{-\frac{23}{20}}
Dividing by -\frac{23}{20} undoes the multiplication by -\frac{23}{20}.
x=\frac{-20y-140}{23}
Divide 7+y by -\frac{23}{20} by multiplying 7+y by the reciprocal of -\frac{23}{20}.
\frac{-23}{20}x-y=7
Expand \frac{-2.3}{2} by multiplying both numerator and the denominator by 10.
-\frac{23}{20}x-y=7
Fraction \frac{-23}{20} can be rewritten as -\frac{23}{20} by extracting the negative sign.
-y=7+\frac{23}{20}x
Add \frac{23}{20}x to both sides.
-y=\frac{23x}{20}+7
The equation is in standard form.
\frac{-y}{-1}=\frac{\frac{23x}{20}+7}{-1}
Divide both sides by -1.
y=\frac{\frac{23x}{20}+7}{-1}
Dividing by -1 undoes the multiplication by -1.
y=-\frac{23x}{20}-7
Divide 7+\frac{23x}{20} by -1.
