Answer: 3

Explanation:

I distributed 4 to the terms inside the parenthesis. 4 multiplied by 5 is 20 and 4 multiplied by negative x is negative 4 x. Then I subtracted 20 from 8 and that equals -12. Then I divide negative 4 x from -12 and that equals 3. I hope it helps!

Answer:


\boxed{ \bold{ \huge{ \boxed{ \sf{x = 3}}}}}

Explanation:


\sf{4(5 - x) = 8}

Distribute 4 through the parentheses


\longrightarrow{ \sf{4 * 5 - 4 * x = 8}}


\longrightarrow{ \sf{20 - 4x = 8}}

Move 20 to right hand side and change its sign


\longrightarrow{ \sf{ - 4x = 8 - 20}}

Subtract 20 from 8


\longrightarrow{ \sf{ - 4x = - 12}}

Divide both sides by -4


\longrightarrow{ \sf{ ( - 4x)/( - 4) = ( - 12)/( - 4)}}

Calculate


\longrightarrow{ \sf{x = 3}}

Hope I helped!

Best regards! :D
