It seems like there's a formatting issue with your question. However, I'll try to solve the simultaneous equations using the elimination method.

Let's assume the equations are:

1) 2x + 5y = 12
2) 3x - 4y = 20

Step 1: Multiply the first equation by 4 and the second equation by 5 to make the coefficients of y the same in both equations:

1) 8x + 20y = 48
2) 15x - 20y = 100

Step 2: Add the two equations together:

23x = 148

Step 3: Solve for x:

x = 148 / 23
x = 6.43 (rounded to two decimal places)

Step 4: Substitute x = 6.43 into the first equation:

2(6.43) + 5y = 12
12.86 + 5y = 12
5y = 12 - 12.86
5y = -0.86
y = -0.86 / 5
y = -0.17 (rounded to two decimal places)

So, the solution to the simultaneous equations is x = 6.43 and y = -0.17.
