Solve for the solution/root of each first-degree equation.
1.
-x +7 = 2
2.
5a = 95
3.
4 = 15
4.
3n + 7 = -15
5.
6c – 35 = c + 10
6.
0.5y + 1.2 = 1
7.
8 + 2(m - 5) = m+ 6
8.
= 5
3
+ 7
-4
= x + 3

Solve each of the following problems completely.
1. Find five consecutive even integers whose sum is 110.
2. Jim is twice as old as his sister. Five years from now, the sum of their ages will be
91. How old is Jim now?
3. The width of a rectangle is 15cm less than its length. The perimeter of the rectangle
is 126cm. Find its dimensions.
4. Dylan invested P120,000, part at 8% and the rest at 10%. If the amount of interest
earned at 8% was four times the amount of interest earned at 10%, how much did
Dylan invest at each rate?
5. It takes a man two hours to mow his lawn, It takes his son three hours to mow the
same lawn. How long will it take if father and son work together to mow the lawn?
6. Solution A is 50% acid and Solution B is 20% acid. How much of each solution is
needed to produce300 liters of a solution that is 30% acid?
7. Wendell leaves his home town traveling 60km per hour. At the same time Randell
leaves home traveling 75 km per hour. The two live 540 km apart and are traveling
to meet each other for a lunch meeting at noon. What time did they leave their
