What are the possible vaules of x it (4x-5)2=49?
d1i1m1o1n [39]

\boxed{The\:value\:of\:x\:is\:7.375.}

\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}

(4x - 5)2 = 49 \\ ⇢8x - 10 = 49 \\⇢8x = 49 + 10 \\  ⇢8x = 59 \\ ⇢x =  \frac{59}{8}  \\ ⇢x = 7.375

Therefore, the value of x is 7.375.

{ \bf{ \underbrace{To\:verify :}}}

(4x - 5)2 = 49 \\ ⇢(4 \times 7.375 - 5)2 = 49 \\ ⇢(29 .5 - 5)2 = 49 \\ ⇢24.5 \times 2 = 49 \\ ⇢49 = 49 \\ ⇢ L.H.S.=R. H. S

Hence verifed.

What is -2/5y = 4 ?????????
Anit [1.1K]
-2 / 5y = 4

Multiply both sides by 5y:

-2/ 5y * 5y = 4 * 5y

refine: -2 = 20 y

Switch sides:

20 y = - 2

Divide both sides by 20

20 y / 20 = - 2 / 20

y = -1/10

hope this helps!
