Answer:

Explanation:

Given the simultaneous equation

4x-5y+16 =0 ....... 1

2x+y-6 =0 ...... 2

Let us solve to get the variable x and y:

The equation becomes

4x-5y =-16 ........ * 1

2x+y =6 ...... *2

Using Elimination method

Multiply eqn 1 by 1 and eqn 2 by 2

4x-5y =-16

4x+2y =12

Subtract resulting equation

-5y-2y = -16-12

-7y = -28

solve for y

-7y/-7 = -28/-7

y = 4

Substitute y = 4 into equation 2 to get x

2x+y =6

2x + 4 = 6

2x = 6-4

2x = 2

x = 2/2

x = 1

hence x is 1, y is 4
