4<br> Subtract. Write the expression below in simplest form.<br> (-x + 3) - (4x-10)
ycow [4]

Answer:

Step-by-step explanation:

(-x + 3) - (4x - 10)

= - x + 3 - 4x + 10 (because when you see the minus sign you have to change all the sign inside the bracket)

= -5x + 13 (this step is just subtract -x and -4x and 10 + 3)
