Question

(3х-1)+(х+3)=20

Answer 1

Ответ : х1 = 1; х2 = -1.

Answer 2

To solve the equation (3x-1) + (x+3) = 20, follow these steps:

Step 1: Combine like terms on the left-hand side (LHS) of the equation: (3x - 1) + (x + 3) = 4x + 2

Step 2: Set the equation equal to the right-hand side (RHS) value: 4x + 2 = 20

Step 3: Isolate the variable x on one side of the equation. To do this, subtract 2 from both sides: 4x = 20 - 2 4x = 18

Step 4: Finally, solve for x by dividing both sides by 4: x = 18 / 4 x = 4.5

Therefore, the solution to the equation is x = 4.5.
