Let the shirts be x and the slacks be y and form a simultaneous equation:-
2(2x+1y = 55)
1x+2y = 68
Multiply all terms in the top equation by 2:-
4x+2y = 110
1x+2y = 68
Subtract the equations to eliminate y:-
3x = 42
Divide both sides by 3 to find the value of x:-
x = 14
Substitute the value of x into the original equations to find the value of y:-
x = 14 and y = 27
Therefore a shirt cost 14 and and a pair of slacks cost 27
