7(2b – 5) + 3 = 10

when doing algebra always remember PEMDAS..(Please Excuse My Dear Aunt Sally) know as Parenthesis, Expontent, Multiplication, Division, Addition, Subtraction

step 1: get rid of parenthesis

Multiply 7 by each number in Parenthesis.. 14b - 35

now the problem should look like: 14b - 35 + 3 =10

Step 2: adding on the same side of the equation

isolate the problem will read as: (-35 + 3) negative plus a positive means subtract therefore the answer will be -32

now the problem will read as 14b - 32 = 10

step 3: moving tumblers to the side of the equation and changing the ssign now

-32 becomes 32

Therefore add 32 + 10 = 42

the problem reads 14b = 42

Step 4: isolate lithe letter by dividing

42/14 = 3

b = 3

## Comments

7(2b - 5) + 3 = 10; or, distributing (removing parentheses), 14b - 7*5 + 3 = 10; or, 14b - 35 + 3= 10; or, 14b - 32 = 10; then add 32 to each side of the equation ---> 14b = 42; then divide each side of equation by 14 ---> b = 42/14 = 21/7 = 3;
