Answer: x = 3
Step-by-step explanation:
9 - 2x = 4x - 9
18 -2x = 4x
18 = 6x
x = 3
Let's make these two fractions have a common denominator and an improper fraction:
1 1/8 = 9/8 = 63/56
2 3/7 = 17/7 = 136/56
63/56 + 136/56 = 199/56 = 3 31/56
So in total, he practiced 3 31/56 hours this week.
He practiced 1 17/56 hours longer on Tuesday than Monday.
Ac - ab = 2
Factor out a
a(c-b) = 2
Then divide the expression by c-b to solve for a.
Do this on both sides.
a(c-b)/(c-b) = 2/(c-b)
a = 2/c-b
The solution is a = 2/c-b.
