It would be 60. He sold his painting for 50 which was 10 less that the original price. So 50+10=60
54 is th answer because ther is 6 units on one side and 9 units in the other and when you times you get this I think
x - 14 would be the equation
Does this help? Not really sure what you are asking.
Ok, so you have your equation, 5·x+5-(5x+25).
First, do the prathases, so you have, 5x+5-5x-25.(5·x also means 5x)
Now, you need to combine like terms, and through that the xs cancel out, so you are left with -20 as you answer.
