x = -0.78 , -2.72 if (2x + 5)/3 = 1/(4x + 4)
Step-by-step explanation:
if
(2x + 5)/3 = 1/(4x + 4)
=> (2x + 5)(4x + 4) = 3
=> 8x² + 8x + 20x + 20 = 3
=> 8x² + 28x + 17 = 0
=> x =( - 28 ± √28² - 4*8*17 )/(2 * 8)
=> x = (-28 ± 15.49)/16
=> x = -0.78 , -2.72

x=4/3
Step-by-step explanation:
2x+5/3=1/4x+4
2x-1/4x=-5/3+4
8x-1/4=-5+12/3
7x/4=7/3
7x=7/3×4
7x=28/3
x=28/3÷7
x=28/3×1/7
x=4/3
Hope this helps you guys though✨✨
