#2.6A
calculate the exact solution of two simultaneous equations in two unknowns x+y=14,x−y=2x + y = 14, x - y = 2x+y=14,x−y=2 2a+5b=12,3a+b=52a + 5b = 12, 3a + b = 52a+5b=12,3a+b=5 Higher only 2x+3y=17,3x−5y=352x + 3y = 17, 3x - 5y = 352x+3y=17,3x−5y=35
#2.6B
interpret the equations as lines and the common solution as the point of intersection
