Question

Solve and check 5x-7=2x+8​

Answer 1

Answer:

Step-by-step explanation:

5x - 7 = 2x + 8

5x - 2x = 7 + 8

3x = 15

x = 15/3 = 5

Check,

L.H.S= 5x - 7

5*5 - 7 = 25 - 7

=18

R.H.S = 2x+8

2*5 + 8 = 10 + 8

=18

Hence L.H.S = R.H.S Proved

Answer 2

$\huge\mathfrak\blue{Answer}$

$= > 5x - 7 = 2x + 8$

$= > 5x - 2x = 8 + 7$

$= > 3x = 15$

$= > x = \frac{15}{3}$

$= > x = 5$

Hence x = 5

$\huge\mathfrak\green{Verification}$

Putting the value of x

$= > 5x - 7 = 2x + 8$

$= > 5(5) - 7 = 2(5) + 8$

$= > 25 - 7 = 10 + 8$

$= > 18 = 18$

Hence, Verified ✔️
