Question

3(M-4) -3 =M solve this problem​

Answer 1

Answer:

3(M-4) - 3 = M

3M-12-3 =M

3M-M=15

2M = 15

M = 15/2

M = 7.5

Answer 2

$\bigstar \large \purple{ \pmb{ \sf Answer}}$

$: \implies \sf 3(m - 4) - 3 = m$

$: \implies \sf 3m - 12 - 3 = m$

$: \implies \sf 3m - m = 12 + 3$

$: \implies \sf 2m = 15$

$: \implies {\boxed {\pink{ \frak m = \dfrac{15}{2} }}} \bigstar$

$\bigstar \large \purple{ \pmb{ \sf Verification}}$

$\dag \underline \frak{substituting \: the \: above \: value \: of \:m \: in \: equation }$

$: \implies \sf 3 \bigg( \dfrac{15}{2} - 4 \bigg )- 3 = \dfrac{15}{2}$

$: \implies \sf 3\bigg( \dfrac{15 - 8}{2} \bigg) - 3 = \dfrac{15}{2}$

$: \implies \sf 3 \times \dfrac{7}{2} - 3 = \dfrac{15}{2}$

$: \implies \sf \dfrac{21}{2} - 3 = \dfrac{15}{2}$

$: \implies \sf \dfrac{21 - 3}{2} = \dfrac{15}{2}$

$: \implies {\boxed {\pink{{ \frak{ \dfrac{15}{2} = \dfrac{15}{2} }}}}} \bigstar$

L.H.S = R.H.S

hence Verified :D
