Question

solve this mates 27 solve this problem please​

Answer 1

Answer:

ok

Step-by-step explanation:

27 - (i)

⇒8x+4 = 3(x-1) + 7

Multiply 3 by x and -1

⇒8x + 4 = 3x -3 + 7

⇒8x + 4 = 3x +7 - 3

⇒8x + 4 = 3x + 4

Now transpose 3x to LHS and +4 to RHS

Hence,

⇒8x-3x = 4-4

⇒5x = 0

⇒x = 0

now 27 --(ii)

⇒$x = \frac{4}{5}(x+10)$

Multiply the numerator , i.e, 4 to x and +10 .

HENCE,

$x = \frac{4x+40}{5}$

Transposing 5 to LHS , we get

5x = 4x + 40

5x-4x = 40

x = 40
