Answer: 3
Step-by-step 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:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 3}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{4(5 - x) = 8}[/tex]
Distribute 4 through the parentheses
[tex] \longrightarrow{ \sf{4 \times 5 - 4 \times x = 8}}[/tex]
[tex] \longrightarrow{ \sf{20 - 4x = 8}}[/tex]
Move 20 to right hand side and change its sign
[tex] \longrightarrow{ \sf{ - 4x = 8 - 20}}[/tex]
Subtract 20 from 8
[tex] \longrightarrow{ \sf{ - 4x = - 12}}[/tex]
Divide both sides by -4
[tex] \longrightarrow{ \sf{ \frac{ - 4x}{ - 4} = \frac{ - 12}{ - 4}}} [/tex]
Calculate
[tex] \longrightarrow{ \sf{x = 3}}[/tex]
Hope I helped!
Best regards! :D
