Find-x when x=- 7/51
would -x = 7/51
To find the value of x when x = -7/51, you simply substitute -7/51 into the equation or expression where x is given.
For example, if you were given the equation 2x + 3 = 0 and asked to find the value of x when x = -7/51, you would substitute -7/51 in place of x:
2(-7/51) + 3 = 0
Now, simplify the equation:
-14/51 + 3 = 0
To combine the fractions, find a common denominator:
-14/51 + (3 * 51/51) = 0
-14/51 + 153/51 = 0
Now, add the fractions:
(153 - 14) / 51 = 0
139/51 = 0
Since 139/51 does not equal 0, x = -7/51 is not a solution to the equation 2x + 3 = 0.
If you have a different equation or expression, substitute -7/51 into it and perform the necessary calculations to find the value of x.
