Solve the System of Inequalities 3x-91>-87 ; OR , 21x-17>25

$3 x - 91 > - 87$ ; OR , $21 x - 17 > 25$

Solve $3 x - 91 > - 87$ for $x$ .

Move all terms not containing $x$ to the right side of the inequality.

Add $91$ to both sides of the inequality.

$3 x > - 87 + 91$

Add $- 87$ and $91$ .

$3 x > 4$

Divide each term in $3 x > 4$ by $3$ and simplify.

$\frac{3 x}{3} > \frac{4}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 x}{3} > \frac{4}{3}$

Divide $x$ by $1$ .

$x > \frac{4}{3}$

Solve $21 x - 17 > 25$ for $x$ .

Move all terms not containing $x$ to the right side of the inequality.

Add $17$ to both sides of the inequality.

$21 x > 25 + 17$

Add $25$ and $17$ .

$21 x > 42$

Divide each term in $21 x > 42$ by $21$ and simplify.

Divide each term in $21 x > 42$ by $21$ .

$\frac{21 x}{21} > \frac{42}{21}$

Simplify the left side.

Cancel the common factor of $21$ .

Cancel the common factor.

$\frac{21 x}{21} > \frac{42}{21}$

Divide $x$ by $1$ .

$x > \frac{42}{21}$

Simplify the right side.

Divide $42$ by $21$ .

$x > 2$

The result can be shown in multiple forms.
