Question

question 22 (mandatory) (1 point) if (x - 1=4), then (x) is equal to a) 6 b) 4 c) 3 d) 5

Explanation:

Step1: Assume the equation is \(x - 1=4\) (assuming the original equation is mis - typed and it should be something like this for a solvable linear equation).

Add 1 to both sides of the equation \(x-1 = 4\).
The operation is \(x-1 + 1=4 + 1\).

Step2: Simplify the equation.

On the left - hand side, \(x+( - 1+1)=x\), and on the right - hand side \(4 + 1=5\). So \(x = 5\).
