Answer 2

Solution to the Equations:

a) To solve the equation (x - 152) - 59 = 6018, we can start by simplifying the equation:

x - 152 - 59 = 6018

Combine like terms:

x - 211 = 6018

Next, isolate the variable x by adding 211 to both sides of the equation:

x - 211 + 211 = 6018 + 211

Simplify:

x = 6229

Therefore, the solution to the equation is x = 6229.

b) To solve the equation 6 + 975 - 361 = 14625, we can simplify it:

6 + 975 - 361 = 14625

Combine like terms:

981 - 361 = 14625

Next, subtract 361 from 981:

981 - 361 = 14625

Simplify:

620 = 14625

However, this equation does not have a valid solution because 620 is not equal to 14625.

c) To solve the equation (30 + 142 + 2) / 3 = 876 + 49, we can simplify it:

(30 + 142 + 2) / 3 = 876 + 49

Combine like terms:

174 / 3 = 876 + 49

Simplify:

58 = 876 + 49

However, this equation does not have a valid solution because 58 is not equal to 876 + 49.

d) To solve the equation 51 + 815 = (p - 975) + 1205, we can simplify it:

51 + 815 = (p - 975) + 1205

Combine like terms:

866 = p - 975 + 1205

Next, simplify the equation:

866 = p + 230

To isolate the variable p, subtract 230 from both sides of the equation:

866 - 230 = p + 230 - 230

Simplify:

636 = p

Therefore, the solution to the equation is p = 636.

e) To solve the equation 13x + 15x - 24 - 60 = 18y + 7y - 10 + 12, we can simplify it:

28x - 84 = 25y + 2

Next, let's isolate the variables x and y. We can start by moving the terms involving x to one side of the equation and the terms involving y to the other side:

28x - 25y = 84 + 2

Simplify:

28x - 25y = 86

Therefore, the solution to the equation is 28x - 25y = 86.
