2x-5y=4. 2x−5y=4. Add 5y to both sides. Add 5y to both sides.
2x=4+5y. 2x=4+5y. The equation is in standard form. The equation is in standard form.
2x=5y+4. 2x=5y+4. Divide both sides by 2. ...
\frac{2x}{2}=\frac{5y+4}{2} 22x=25y+4 Dividing by 2 undoes the multiplication by 2. ...
x=\frac{5y+4}{2} x=25y+4 Divide 4+5y by 2.
Step-by-step explanation: How do I determine how many solutions an equation has?
If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions.
