Solve the equation for the variable b: ab - 2c = 4

b : ab = a

a - 2c = 4

- 2c = 4 - a

Step-by-step explanation:

hope it helps

b = (4+2c)/a

Step-by-step explanation:

ab - 2c = 4

Add 2c to each side

ab - 2c+2c = 4+2c

ab = 4+2c

Divide each side by a

ab/a = (4+2c)/a

b = (4+2c)/a

you cant answer this dummy

step-by-step explanation:

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
