How do I Solve this b + 7 = 20?

b + 7 = 20

b = 20 - 7

b = 13

Hope this helps.

b + 7 = 20
b = 20 - 7
b = 13

you have to look at the question.. b is replacing a number that can be added to 7 to give u 20..

what plus 7 euals 20?

you know that 13 + 7 = 20

so thats your answer..dont get confused by the letters their only there to freak u out lol in math the letters will always come out to be a number

b = 13

subtract seven on both sides...
b+7-7=20-7

the seven on the left cancel out and then the other side is 13
b=13

B = 13.

B+7=20 rewrite to 20-7=B B=13

b = 20 -7 = 13

hahahahahahahahahahahaha

13

b= 13

For simple addition problems involving algebra do the answer (the number after the equals sign) take away the other number you've got. This will give you the value of the missing number.
