Show that the equations 5x + 6y = 3 = 0 and 4y + x = 5 are consistent and hence, solve for x and y.

Is the pair of equations 3x - 5y =6 and 4x -6y =7 consistent ? Justify your answer.

Show that the following system of linear equations is consistent and hence solve the equations: 2x + 3y = 1 and 3x -y = 7

Show that the following equations are consistent: 5x+6y=11,x+y=2,2x+3y=5

Solve the simultaneous equations graphically. 5x - 6y + 30 = 0, 5x + 4y - 20 =0

Solve: 5x-6y+30=0 and 5x+4y-20=0

Show that the following equations are consistent: 7x-4y+12=0,8x-y+3=0,x+3y-9=0

Solve the pair of equations : (3)/(x) + (2)/(y) = 7 (5)/(x) - (4)/(y) = 13 Hence find the value of 27x - 12y .
