Give work for equations following:<br><br> -x+2y&lt;-4<br> 2x+3y&gt;6<br><br> thanks sooooo much!!!!
Schach [20]

Answer: See below

Step-by-step explanation:

A) -x+2y < -4

-x+2y-2y < -4-2y

-x < -4-2y

Multiply both sides by -1 and reverse the inequality:

\left(-x\right)\left(-1\right) > -4\left(-1\right)-2y\left(-1\right)

x > 4+2y

B) 2x+3y > 6

2x+3y-3y > 6-3y

2x > 6-3y

\frac{2x}{2} > \frac{6}{2}-\frac{3y}{2}

x > \frac{6-3y}{2}\\x > 3-\frac{3y}{2}
