X + 2/3 = −4 A x = −3 1/3x = −313

B x = −4 2/3x = −423

C x = 3 1/3x = 313

D x = 4 2/3

b.

Step-by-step explanation:

x + 2/3 = -4 [multiply the entire equation by 3 to get rid of denominator]

3x + 2 = -12  [subtract 2 from both sides of equation]

3x = -14 [divide by 3 to isolate x]

x = -14/3 or -4 2/3

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.
