Answer 3

Solving the Equations

a) 8 - 5(8 + 3x) = 13

To solve this equation, we'll follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, we'll simplify the expression inside the parentheses: 8 - 5(8 + 3x) = 13 8 - 40 - 15x = 13 -32 - 15x = 13

Next, we'll isolate the variable x by performing the necessary operations: -15x = 13 + 32 -15x = 45

Finally, we'll solve for x: x = 45 / -15 x = -3

b) x - x/30 = 29/15

To solve this equation, we'll first simplify the expression: x - x/30 = 29/15 30x/30 - x/30 = 29/15 (30x - x) / 30 = 29/15 29x / 30 = 29/15

Next, we'll isolate the variable x by performing the necessary operations: 29x = 30 * 29/15 29x = 58 x = 2

Conclusion

The solutions to the given equations are: a) x = -3 b) x = 2
