WebNov 14, 2012 · Using substitution to solve the first system of eqations. step 1: isolate either x or y in one of the equations - I chose to isolate x in x - 3y = 3. x - 3y = 3. +3y +3y. x = 3 + 3y. step 2: plug that value of x into the other equation. -x + 2y = 7 (plut in your x and solve for y!) - (3+3y) + 2y = 7 (now y is the only varialbe in your equation!) Web2.2 Solving x2-10x+29 = 0 by Completing The Square . Subtract 29 from both side of the equation : x2-10x = -29. Now the clever bit: Take the coefficient of x , which is 10 , divide by two, giving 5 , and finally square it giving 25. Add 25 to both sides of the equation : On the right hand side we have : phl21a
