Answer 2

Given - Sum

Find - Number

Solution - According to the question, the equation that will form is -

$x + \frac{ - 3}{4} = - 1$

Rewriting the equation as per sign convention

$x - \frac{3}{4} = - 1$

Shifting the value of Left Hand Side to Right Hand Side. The equation will be -

$x = - 1 + \frac{3}{4}$

Performing addition of values on Right Hand Side

$x = \frac{( - 1 \times 4) + (3 \times 1)}{4}$

Performing multiplication of numerators

$x = \frac{ - 4 + 3}{4}$

Performing addition of numerators

$x = \frac{ - 1}{4}$

Hence, the value of x should be -1/4.
