what is the solution of x-5y=10 and 2x-10y=20
x = 12 y = 2 (12,2) satifies the equation
There is one solution. To find it, divide both sides of the equation by 2. This leaves you with x=5, where 5 is your solution.
An expression does not include an equals sign (=) For eg: 2x+3 would not be an equation but an expression However, 2x+3=0, is definitely an equation with a solution x= -3/2. An expression does not have a definite solution. An expression is a set of terms with mathematical operations combining them. An equation consists of two expressions with an equals sign between them. An expression is a collection of terms and does not have an = sign An equation is a collection of terms but has an = sign between them.
2x + 14 = 0Subtract 14 from each side of the equation: 2x = -14Divide both sides of the equation by 2: x = -7You can also obtain solutions to equations by visting wolframalpha.com. Enter solve 2x+14=0, for example. You can click on the 'step-by-step' button to see how the equation was solved.
