Answer:

$\boxed{\bold{True}}$

Step By Step Explanation:

Equation One:

Multiply Both Sides By One (Reverse The Inequality)

$\bold{\left(-\frac{2}{5}x\right)\left(-1\right)$

Simplify

$\bold{\frac{2}{5}x$

Multiply Both Sides By 5

$\bold{5\cdot \frac{2}{5}x$

Simplify

$\bold{2x$

Divide Both Sides By 2

$\bold{\frac{2x}{2}$

Simplify

$\bold{x$

-------

Equation Two:

Subtract $\bold{\frac{3}{4} }$ From Both Sides

$\bold{-x+\frac{3}{4}-\frac{3}{4}$

Simplify

$\bold{-x$

Multiply Both Sides By -1 (Reverse The Inequality)

$\bold{\left(-x\right)\left(-1\right)>\frac{37\left(-1\right)}{4}}$

Simplify

$\bold{x>-\frac{37}{4}}$
