Question

X-86 = 42 solve the following​

Answer 1

We are given a one-step linear equation in one variable, and our task is to solve it for x, which is the variable of this equation. To find the value of x, I am going to move 86 to the other side, while changing its sign - here it's subtracted from both sides, so I'll add it to both sides.

`\textsc{equation:}`

⇒ x - 86 = 42

We proceed to add 86 to both sides ...

⇒ x = 128

Therefore, x = 128.

Answer 2

x = 128

Explanation:

given

x - 86 = 42 ( isolate x on the left side by adding 86 to both sides )

x - 86 + 86 = 42 + 86 , that is

x = 128
