Question

what should be subtracted from -3/4 to get 1/2?​

Answer 1

Answer:

-5/4

Step-by-step explanation:

1. (-3/4)-x=1/2

2.(-3-4x)/4=1/2

3. (-3-4x)=1/2×4

4. -4x=2+3

5. x=(-5/4)

Answer 2

$\bold{Let \: , \: The \: Unknown \: Number \: Be \: x \: }$

$\bold{According \: To \: The \: Question \: , \: }$

$\bold{ \to \: \: \frac{ - 3}{4} - x \: = \: \frac{1}{2} } \\ \\ \bold{\to \: \: - x \: = \: \frac{1}{2} + \frac{3}{4}} \\ \\ \bold{ \to \: \: - x = \: \: \frac{5}{4}} \\ \\ \bold{ \to \: \: \: \: x = \: - \frac{5}{4} }$

$\underline \bold{ \large{ Verification :- \: }}$

$\bold{ \to \: \: \frac{ - 3}{4} - ( - \frac{5}{4} )\:} \\ \\ \bold{\to \: \: { \frac{ -3 }{4} } + \frac{5}{4} } \\ \\ \bold{ \to \: \: \: \: \: \: \: \: \: \: { \frac{1}{2} }}$

$\underline\bold{ \large{ \: Hence \: Verified \: \: \: \: \:}} \:$
