Answer:
[tex]5\left(x-3\right)-4\left(x-3\right)=x-3[/tex]
Step-by-step explanation:
Given the expression
[tex]5\left(x-3\right)-4\left(x-3\right)[/tex]
solving the expression
[tex]5\left(x-3\right)-4\left(x-3\right)=5x\:-\:15\:-\:4x\:+\:12[/tex]
[tex]= x - 3[/tex]
Thus, the equivalent expression is
[tex]5\left(x-3\right)-4\left(x-3\right)=x-3[/tex]
