Answer 1

Answer:

we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.

Step-by-step explanation:

Given the expression

$4 < -2x + 3 < 9$

SECOND STEP

subtract 3 from the right-hand side as well as on the left-hand side

$4-3 <-2x+3-3<9-3$

SOLVING THE REMAINING COMPLETE COMPRESSION

$1 < -2x < 6$

Divide all parts by -2

• Please note that multiply or divide an inequality by a negative number flips the inequality sign.

so the expression becomes

$\frac{1}{-2}\:<\:\frac{-2x}{-2}\:<\:\frac{6}{-2}$

$\frac{1}{-2}\:>x\:<\:-3$

Hence, from the explanation, we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.
