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

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)

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
