(will give brainliest plus 40 points)solve both equations. show your work. 2/3 x^2+1=55 -2y^3-5=49

First 
23x2+1−1=55−123x2=54Step 2: Divide both sides by 2/3.23x223=5423x2=81Step 3: Take square root.x=±√81x=9 or x=−9x=9 or x=−9

Second:
−2y3−5=49Step 1: Add 5 to both sides.−2y3−5+5=49+5−2y3=54Step 2: Divide both sides by -2.−2y3−2=54−2y3=−27Step 3: Take cube root.y=(−27)(13)y=−3y=−3

54= 2/3x^2

44= -2y^3

hope it helps since we cant define y just kidding hope his helps im wiehnbgwlk
