Step-by-step explanation:
Simplify the equation for n.
[tex]23 = - 4n + 15 - 8n + 2[/tex]
[tex]23 = - 12n + 17[/tex]
Subtract 17 from both sides:
[tex]6 = - 12n[/tex]
Divide each side by -12:
[tex] - \frac{1}{2} = n[/tex]
Appropriate Question :
Solve for n :
Solution :
[tex]\qquad{ \dashrightarrow \: { {{ \sf{ 23 = -4n + 15 - 8n + 2 }}}}\:}[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ 23 = -4n - 8n + 15 + 2 }}}}}\:[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ 23 = -12n + 17 }}}}}\:[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ 12 n= 17 - 23 }}}}}\:[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ 12n = - 6 }}}}}\:[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ n = - \dfrac{6}{12} }}}}}\:[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ n = - \dfrac{1}{2} }}}}}\:[/tex]
