How to solve a linear equation for y
WebA linear equation is an equation with variable (s) to the first power and one or more constants. For example, in the linear equation \blueD {2}x+\maroonD {3}=\maroonD {4} 2x+3 = 4: x x is the variable, which represents a number whose value we don't know yet. \blueD {2} 2 is … WebThe Linear Combination Method , aka The Addition Method , aka The Elimination Method. Add (or subtract) a multiple of one equation to (or from) the other equation, in such a way that either the x -terms or the y -terms cancel out.Then solve for x (or y , whichever's left) and substitute back to get the other coordinate.
