Question

Solve by transposition and verify.
(v) 2x 1 = 3x + 7
​

Answer 1

Step-by-step explanation:

Given equation is 2x-1=3x+7

=>2x-1=3x+7

=>2x-3x=7+1

=>-x=8

=>x=-8

The value of x=-8

The solution is -8

Verification:-

LHS:-

2x-1

=>2(-8)-1

=>-16-1

=>-17

RHS:-

3(-8)+7

=>-24+7

=>-17

LHS=RHS is true for x=-8

Answer 2

Answer:

Step-by-step explanation:

$2x*1=3x+7\\2x=3x+7\\2x-3x=7\\-x=7\\x=-7$

Verify

$2*(-7)*1=3*(-7)+7\\-14=-21+7\\-14=-14\\Hence, Verfied$
