Question

3(x+2)-2(x-1)=7
solve the algebraic expression using transposition method
class 6

Answer 1

Ans= 3(x+2) - 2(x-1) = 7

= 3x + 6 - 2x -1 =7

=3x-2x +6-1 = 7

=x +5 = 7

= x =7-5

=x=2 ans

$\large\bf{{\underline{To~solve}}:}$

$\tt{~~~~~~~~3(x+2)-2(x-1)=7}$

$\tt{:\longrightarrow (3x+6)+(-2x+2)=7}$

$\tt{:\longrightarrow 3x+6-2x+2=7}$

$\tt{:\longrightarrow (3x-2x)+(6+2)=7}$

$\tt{:\longrightarrow x+8=7}$

$\tt{:\longrightarrow x=7-8}$

$\tt{:\longrightarrow x={\large{\orange{\underline{\boxed{\bf -1}}}}}~~~~~~~{\huge{\orange{\bf ✓}}}}$
