Question

solve
7x -3 = 3x -12​

Answer 1

7x -3 = 3x -12

=>7x-3x= -12+3

=>3x= -9

=>x= -9/3

=>x= -3

Answer 2

Given :

• $\rm{7x -3 = 3x -12}$

To find :

• The value of x

Solution :

Here we will use the concept of linear equations to find the value of x.

• $\sf{7x -3 = 3x -12}$

${: } \to \sf7x - 3x = - 12 + 3$

${:} \to \sf4x = - 9$

${: } \to \sf{x = \boxed {\bf {\dfrac{ - 9}{4} }}}$

Answer :

• The value of x is -9/4
