Question

Follow the steps to find the value of x.2x−5=7

a) x=6

b) x=4

c) x=3

d) x=8

Answer 1

Answer: a) x = 6

Step-by-step explanation:

To find the value of x, we must change the arrangement of the expression to leave the x variable by itself. To do this, we solve by moving the accompanying values to the other side of the equal sign with "opposite" operations.

2x - 5 = 7

We move the 5 to the other side by adding it to cancel out that term to zero on the left.

2x - 5 + 5 = 7 + 5

2x = 12

We divide the 2 that is the coefficient of the variable to isolate the variable.

`(2x)/(2)` =
`(12)/(2)`

x =
`(12)/(2)`

From here, we can divide normally to simplify our equation and give us our answer.

x = 6

Answer 2

To find the value of x in the equation 2x−5=7, add 5 to both sides to cancel out the -5, then divide both sides by 2 to solve for x. The value of x is 6.

Step-by-step explanation:

To find the value of x in the equation 2x−5=7, we can solve for x by isolating it on one side of the equation. First, we add 5 to both sides to cancel out the -5. This gives us 2x = 12. Next, we divide both sides by 2 to solve for x. So, x = 6.
