First, we know that y is equal to -8x, so we can move the -8x to replace y in the first equation, then in the first equation we get -8x=6x-14, subtract 6x on both sides, -14x=-14, x=1

Answer:
<u>30 pesos</u>
Step-by-step explanation:
<u>Given</u>
- Had 200 pesos originally
- spends 'y' pesos on a notebook
- Bought 4 colored pens with the rest of the money
<u>Solving</u>
- Let money of the pen = x, money of notebook = y

- 4x + 80 = 200
- 4x = 120
- x = <u>30 pesos</u>
Answer:
g = 3/7
Step-by-step explanation:
7/(3/2)
= 7 x (2/3)
= ( 2 x 7 )/3
= 14/3
14/3 = 2/g
Cross multiply,
14 x g = 3 x 2
g = ( 3 x 2 )/14
14 can be written as 2 x 7.
g = ( 3 x 2 )/( 2 x 7 )
2 in both numerator and denominator gets cancelled.
g = 3/7
