Question

Find the value of b. -11b + 7 = 40

Answer 1

Answer:

b = -3

Step-by-step explanation:

-11b + 7 = 40

In equations, we want to find the value of 'b' by rearranging the equation to get all the numerical values of on one side and the values with letters on the other sides, doing this will provide an easier way to solve the equation. Also we have to do the specified operation on both sides because if you only do it on one then the whole equation has changed and the solution will be different so

- 11b + 7 = 40

Minus 7 from both sides to isolate -11b

-11b = 33

→ Divide both sides by -11 to isolate b

b = -3

Answer 2

Answer:

-3

Step-by-step explanation:

-11b + 7 = 40

Subtract both sides by 7.

-11b = 33

Divide both sides by -11.

b = -3
