Question

60-15(x-3)=45

Answer 1

60 - 15(x-3) = 45

15(x-3) = 15

x-3 = 1

x=4

Answer 2

\(60-15\left(x-3\right)=45\)

\(\Leftrightarrow60-15x+45=45\)

\(\Leftrightarrow15x=60\)

\(\Leftrightarrow x=4\)

Answer 3

\(60-15\left(x-3\right)=45\)

\(\Rightarrow15\left(x-3\right)=60-45\)

\(\Rightarrow15\left(x-3\right)=15\)

\(\Rightarrow x-3=15\div15\)

\(\Rightarrow x-3=1\)

\(\Rightarrow x=1+3\)

\(\Rightarrow x=4\)

Answer 4

60 - 15 ( x - 3 ) = 45

=> 60 - 15x + 45 = 45 

=> 15x = 60

=> x = 4
