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
