    Simplifying 14x + -11y = 16 Solving 14x + -11y = 16 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '11y' to each side of the equation. 14x + -11y + 11y = 16 + 11y Combine like terms: -11y + 11y = 0 14x + 0 = 16 + 11y 14x = 16 + 11y Divide each side by '14'. x = 1.142857143 + 0.7857142857y Simplifying x = 1.142857143 + 0.7857142857y

    Simplifying 3x + -2y = 2 Solving 3x + -2y = 2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2y' to each side of the equation. 3x + -2y + 2y = 2 + 2y Combine like terms: -2y + 2y = 0 3x + 0 = 2 + 2y 3x = 2 + 2y Divide each side by '3'. x = 0.6666666667 + 0.6666666667y Simplifying x = 0.6666666667 + 0.6666666667y

    there are 4 methods to solve simultaneous equations. don't have much time right now to be detailed.

    for this we will use elimination. the objective is to make the coefficient of one variable equal and opposite so when you add the equivalent equations that variable is eliminated leaving one equation with one variable. solve for that then use the value to substitute in the expression for the other (the eliminated) variable.

    simultaneous eqn solution means the same (x,y) set works for each of the original eqns.

    REVIEW start by eliminating y make the coefficient equal and opposite multiply each equation with the factor necessary to be equal and opposite add the equations one eqn with x solve for x x = -2 use -2 in either equation solve for y
