How do you solve #10b + 18= 8b + 4#?

Answer 1

Savannah Anderson

#b=-7#

Step 1: Subtract 8b from both sides.

#10b+18−color(blue)(8b)=8b+4−color(blue)(8b)#

#2b+18=4#

Step 2: Subtract 18 from both sides.

#2b+18−color(green)(18)=4−color(green)(18)#

#2b=−14#

Step 3: Divide both sides by 2.

#(cancel2b)/cancelcolor(orange)(2)=(−14)/color(orange)(2)#

#b=−7#

To solve the equation 10b + 18 = 8b + 4, you would first combine like terms. Then, isolate the variable b by moving all terms containing b to one side of the equation and the constants to the other side.

10b - 8b = 4 - 18

Simplify both sides:

2b = -14

Divide both sides by 2 to solve for b:

b = -7

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.
