Problem

Find the multiplicative Inverse of x:
3x + 12 = − 5

2

Step

Let’s solve for x

3x + 12 = - 5

3

Step

To simplify the equation, subtract 12 from both sides

3x + 12 - 12 = - 5 - 12

\$ 3x = (- 17) \$

\$ x = - (17/3) \$

4

Formula:

The multiplicative inverse of

\$ a/b \$ = \$ b/a \$

5

Step

Now, the multiplicative inverse of \$- (17/3)\$ is simply its reciprocal:

Multiplicative inverse of \$ - (17/3) = - (3/17) \$

6

Choice.A

This is the correct choice for the multiplicative inverse of the given expression

\$- (3/17)\$

7

Choice.B

This option represents the reciprocal of the correct answer. It’s the inverse of \$-3/17\$, but we’re looking for the inverse of x, not the reciprocal

\$(3/17)\$

8

Choice.C

This option is incorrect because it is the value of x

\$- (17/3)\$

9

Choice.D

This option doesn’t seem to relate to the correct solution. It doesn’t correspond to the multiplicative inverse of x in the given equation

\$(-3)/(-7)\$

Answer

Option

A
