Question

Solve the simultaneous equations below. Show your work clearly,
a)
y-2x = 6
A
y + 2x = 6

Answer 1

Answer:

The solution of the given two equations

  ( x, y) = (0,6)

Step-by-step explanation:

Step(i)

Given equations are

                  y - 2x = 6  ...(i)

                 y + 2x = 6  ...(ii)

Adding (i) and (ii) equations, we get

          y - 2x + y +2x = 6+6

                2 y = 12

                  y =6

Step(ii):-

substitute y =6 in equation (i). we get

               y - 2x =6

              6 - 2x =6

              6-6 =2x

               0 = 2 x

               x = 0

The solution of the given two equations

  ( x, y) = (0,6)
