Hi there!
Answer:
2x−3y=5
Add 3y to both sides of the equation.
2x=3y+5
Divide each term by 2 and simplify.
Divide each term in 2x=3y+5 by 2
2x2=3y2+52
Reduce the expression by cancelling the common factors.
Cancel the common factor.
2/x2=3y2+52 Divide x by 1
x=3y2+52
You can double the fractions, so instead of 14/20 and 15/20 you have 28/40 and 30/40. The fractions still equal the same amount. Between theses two new fractions is the fraction 29/40.
So, 29/40 is between 14/20 and 15/20.
Call b the amount of babysitting hours and 5 the amount of gardening hours.
10b+5g=80
b+g=12
Subtract 5 times the second equation from the first to get:
5b=20
Thus, b=4. g=12-4, or 8. Therefore, Sarah spends 4 hours babysitting and the rest gardening.
4.000 plus 200 plus 90 plus 3
