Solve the simultaneous equations 2x + 3y = 19 , 3x + y = 11
Rearrange to make the y component the subject3y = 19 - 2x , y = 11 - 3xMultiply the second equation by 33y = 33 - 9xEquate to each other19 - 2x = 33 - 9xRearrange7x = 14Divide by 7x = 2Substitute x=2 into one of the equations and solve for yy = 11 - (3 x 2) = 5
