Solution is x = −29 and y = −23 Explanation: To solve system of linear equation in two variables using substitution, one substitutes value ... For the following condensed proof, write an analysis indicating the forward and backward steps and the key questions and answers. Yours is the one that makes no sense at all.

Rewrite the equation as y = x−7 y = x - 7. Use the slope-intercept form to find the slope and y-intercept. Tap for more steps... Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values. Tap for more steps...

Consider x^{7}+y^{7} as a polynomial over variable x. Find one factor of the form x^{k}+m, where x^{k} divides the monomial with the highest power x^{7} and m divides the constant factor y^{7}. One such factor is x+y.
