2x minus 3y equals 11 5x plus 2y equals 18?

Answer 1

Presumably this is a simultaneuos equation question that can be solved using the elimination method:

2(2x-3y = 11)

3(5x+2y = 18)

Multiply all terms in the top equation by 2 and in the bottom by 3:

4x-6y = 22

15x+6y =54

Add both equations together:

19x = 76

Divide both sides by 19 to find the value of x:

x = 4

Substitute the value of x into the original equations to find the value of y:

Therefore: x = 4 and y = -1
