Question

7(x+8)=49

i know the answer but tell me how did you solve it only with numbers and mathematical letters nothing else

Answer 1

I would distribute the 7 to x and 8 by multiplying them by 7 which would give you 7x+56=49. Then I would subtract 56 from 56 and 49 which would give you -7. Now we should have 7x=-7. Now we divide 7x by 7 and -7 which would equal -1.

Answer 2

Answer:
- Divide both sides by 7
x + 8 = 49/7
- Simplify 49/7 to 7
x + 8 = 7
- Subtract 8 from both sides
x = 7 - 8
- Simplify 7 - 8 to -1
x = -1
