Question

solve the following equations and verify your answer 2x+7=3(x-1)​

Answer 1

hey your answer is :-

2x+7=3(x-1)

= 2x + 7 = 3x - 3

= 2x - 3x = - 3 - 7

= - x = - 10

Minus get cancelled

= > x = 10

put x = 10

2x+7=3(x-1)

2 × 10 +7 = 3×10 - 3

20 + 7 = 30 - 3

27 = 27

VERIFIED

Answer 2

$\huge\mathrm\purple{\underline{Answer:}}$

2x + 7 = 3 (x - 1)

2x + 7 = 3x - 3

2x - 3x = - 3 - 7

- x = - 10

x = 10

$\underline{\pink{verification \: by \: substitution \: the \: value \: of \: x \: in \: eq}}$

2 (10) + 7 = 3 (10 - 1)

20 + 7 = 3 (9)

27 = 27

L.H.S. = R.H.S.

hope it helps!❤
