Let A be the number of one-step equations eliminated and B the number of two-step equations eliminated then, 
A + B = 1070 .....Equation (1)
and we are told that, 3A - 2B = 110.....Equation (2)
multiplying Eqn (1) by 2 gives
2A + 2B = 2140........now add Eqn(2)
3A - 2B = 110
5A = 2250 , A = 450
