Question

(x-75)+42=315 792-(x+301)=98

Answer 1

х-75=315-42

х-75=273

х=273+75

х=348

х+301=792-98

х+301=694

х=694-301

х=393

Answer 2

(x-75)+42=315

х-75=315-42

х-75=273

х=273+75

х=348

792-(x+301)=98

х+301=792-98

х+301=694

х=694-301

х=393

Answer 3

To solve the given equations, we'll isolate the variable "x" in each equation. Let's start with the first equation:

1. (x - 75) + 42 = 315

Step 1: Remove the parentheses using the distributive property. x - 75 + 42 = 315

Step 2: Combine like terms on the left side of the equation. x - 33 = 315

Step 3: Isolate the variable "x" by adding 33 to both sides of the equation. x = 315 + 33

Step 4: Perform the addition to find the value of "x". x = 348

Now, let's move on to the second equation:

2. 792 - (x + 301) = 98

Step 1: Remove the parentheses using the distributive property. 792 - x - 301 = 98

Step 2: Combine like terms on the left side of the equation. 491 - x = 98

Step 3: Isolate the variable "x" by subtracting 491 from both sides of the equation.

• x = 98 - 491

Step 4: Perform the subtraction to find the value of "-x".

• x = -393

Step 5: To solve for "x," we need to multiply both sides by -1 to eliminate the negative sign. x = -(-393)

Step 6: Perform the negation of -393 to get the final result. x = 393

So, the solutions to the given equations are: x = 348 (from the first equation) x = 393 (from the second equation)
