Question

7-3x = 5x -3 solve and check plz.... solve it ​

Answer 1

Answer:

5/4

Step-by-step explanation:

7-3x=5x-3

Transporting 3x to RHS and 3 to LHS

7+3=5x+3x

10=8x

x=10/8

=5/4

Verification:

Substitute x as 5/4

7-(3×5/4)=(5×5/4)-3

7-15/4=25/4-3

28/4-15/4=25/4-12/4

(28-15)/4=(25-12)/4

13/4=13/4

Answer 2

$\sf{Answer}$

Step by step explanation:-

To solve :-

7-3x = 5x -3

Solution:-

7 - 3x = 5x -3

Transpose like terms to a side

7 + 3 = 5x + 3x

10 = 8x

Make a subject x

$\sf\dfrac{10}{8}$ = $\sf\dfrac{8x}{8}$

$\sf\dfrac{10}{8}$ = x

$\sf\dfrac{5}{4}$ = x

Verification:

Substuite value of x to get LHS = RHS

7-3x = 5x -3

7 - 3× $\sf\dfrac{5}{4}$ = 5×$\sf\dfrac{5}{4}$-3

7 - $\sf\dfrac{15}{4}$ = $\sf\dfrac{25}{4}$-3

$\sf\dfrac{28-15}{4}$ = $\sf\dfrac{25-12}{4}$

$\sf\dfrac{13}{4}$ = $\sf\dfrac{13}{4}$

Hence

LHS = RHS
