Question

simplify the following 2by 3 +4by 7-2

Answer 1

Answer:

2/3 + 4/7 - 2

LCM = 21

14/21 + 12/21 - 42/21

26/21 - 42/21

= 16/21

Answer 2

Subtracting (1) From (2) :

$\begin{gathered}\sf6d = - 12 \\ \\ \LARGE \purple{ :\longmapsto \underline {\boxed{{\bf d = - 2} }}}\end{gathered}$

:⟼6d= −12

:⟼

d= −2

Putting Value of d in (1) :

\begin{gathered}\sf a + 2 \times ( - 2) = 4 \\ \\ \LARGE\purple{ :\longmapsto\underline {{{\boxed{{\bf a = 8} }}}}}\end{gathered}

a+2×(−2)=4

:⟼

a=8

${\green\longmapsto}\:{\LARGE\green{\boxed{\mathfrak{ItzGurungBoY}}}}$
