How do you solve #-70- 8x = 38- 4x#?

Answer 1

Julia Adams

#x = 27#

To start, we should isolate our x. Then, add 4x and 70 to both sides of this.

#-70 - 8x = 38 -4x#

#-8x = 108 - 4x#

#-4x = 108#

To find x, divide both sides by -4.

#x = -27#

Check:

#-70 - (8 * -27) = 38 - (4 * -27)#

#-70 - (-216) = 38 - (-108)#

#-70 + 216 = 38 + 108#

# 146 = 146#

To solve the equation -70 - 8x = 38 - 4x:

Start by combining like terms on both sides of the equation.
Add 8x to both sides to move all terms involving x to one side of the equation.
Subtract 38 from both sides to isolate the term with x.
Combine constants on both sides of the equation.
Divide both sides by the coefficient of x to solve for x.

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.
