13 - (x+2) = 8
subtract 13 from both sides
-(x+2) = -5
divide by -1 to get rid of negative
(x+2) = 5
subtract 2 from both sides
x=3
Step-by-step explanation:
Let,
- Money received by Jan = 4x
- Money received by Jane = 9x
- Money received by Jello = 6x
According to the question,
→ Money received by Jan = $200
→ 4x = $200
→ x = $200 ÷ 4
→ x = 50 ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀… ( 1 )
Now,
→ Money received by Jane = 9x
→ Money received by Jane = 9($50)
→ <u>Money received by Jane = $450</u> [Ans]
And,
→ Money received by Jello = 6x
→ Money received by Jello = 6($50)
→ <u>Money received by Jello = $300</u> [Ans]
