Question

solve 5 x + 3 = to X + 18​

Answer 1

Given:-

equation:- 5x+3=x+18

To find:-

Value of x?

$\orange{\boxed{\pink{\underline{\red{\mathrm{Proof:-}}}}}}$

→5x+3=x+18

→5x-x=18-3

→4x=15

→x=$\frac{15}{4}$

$\rule{200}{1}$

Answer 2

Solution :

5x + 3 = x + 18

Taking the x terms in left side

$\rightarrow \: \sf{5x - x = 18 - 3} \\ \\ \rightarrow \: \sf{ 4x = 15} \\ \\ \rightarrow \: \boxed{\sf{x = \frac{15}{4} }}$

Checking the answer :

5x + 3 = x + 18

$\sf{Putting \: \bigg( x = \dfrac{15}{4} \bigg) \: in \: above \: equation }$

$\rightarrow \: \sf{ \bigg(5 \times \dfrac{15}{4} \bigg) + 3 = \dfrac{15}{4} + 18 } \\ \\ \rightarrow \: \sf{ \dfrac{75}{4} + 3 = \dfrac{15}{4} + 18 } \\ \\ \rightarrow \: \sf{ \frac{75 + 12}{4} = \frac{15 + 72}{4} } \\ \\ \rightarrow \: \sf{ \frac{86}{4} = \frac{86}{4} }$

LHS = RHS
