Question: 2x - (-1) = 3.

Answer: = 1

Steps below:

NB: We are finding the value of x so therefore, we would need to move everything away from x which we are making the subject of the formula. Remember our signs are opposite when we move to opposite side of the equation so a positive becomes a negative or if it's multiplying on the left then it would be dividing on your right.

……

According to Sign Rules, a negative multiplied by a negative would equal to a positive hence - × (-1) = +1.

Step 1:

2x + 1 = 3

Now we need to have to find for x so we first take away 1 from both sides of the equation and we get…

Step 2:

2x = 3 - 1

2x = 2

We now divide by 2 on both sides of the equation..

Step 3:

X = 2/2

X = 1

Answer 2

Answer:

Step-by-step

2x-3=1

2x=1+3

2x =4

x=2

so, the value of x is 2
