Y-5=3-9 (y+2)
Solve for y
Distribute the 9 to (y+2)
Y-5=3-9y-18
Y-5=-15-9y
+9y to both sides
10y-5=-15
+5 to both sides
10y=-10
÷10 both sides
Y= -1

2 (x-7)-10=12-4x
Solve for X
Distribute 2 to (x-7)
2x-14-10=12-4x
2x-24=12-4x
+4x to both sides
6x-24=12
+24 to both sides
6x=36
÷6 to both sides
X=6

Alex73 [517]

Answer:

3 $\frac{3}{4}$ days

Step-by-step explanation:

Let the amount of work be x.

Daniel:

10 days = x

1 day = $\frac{1}{10}$ x

Father:

6 days = x

1 day = $\frac{1}{6}$ x

Together:

1 day = $\frac{1}{10}$ x + $\frac{1}{6}$ x

= $\frac{6}{60}$ x + $\frac{10}{60}$ x

= $\frac{16}{60}$ x

= $\frac{4}{15}$ x

No. of days = $\frac{15}{15}$ x ÷ $\frac{4}{15}$ x

= $\frac{15}{15}$ x × $\frac{15}{4}$ x

= $\frac{225}{60}$

= 3 $\frac{3}{4}$
