How do you solve #-4y - ( - 10) = - 90#?

Answer 1

Eva Adamson

#y=25#

#-4y-(-10)=-4y+10=-90 " "# you add #-10# to each side

#-4y+10-10=-90-10#

#-4y=-100 " "# divide both sides with #-4#

#y=(-100)/-4#

#y= 25#

To solve the equation -4y - (-10) = -90, you would first simplify the expression inside the parentheses by removing the double negative, which becomes -4y + 10. Then, you combine like terms by subtracting 10 from both sides to isolate the variable term, resulting in -4y = -100. Finally, you divide both sides by -4 to solve for y, yielding y = 25.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
