Solve this simultaneous equation 15x +2y = 4 ; 2x +y = 2

Multiply equation 2 by 2: 4x +2y =4 (equation 3); Subtract equation 3 from equation 1: 15x+2y = 4 - (4x +2y =4) = 11x + 0y =0; 11x = 0; x=0Substitute x with 0 in equation 1: 15(0) +2y =4; 2y=4; y=2Insert x=0 and y=2 in equation 2 to be sure; 2(0)+2=2
