What is the value of n in the equation -1.2(2n+4)+6=-9+4(2n+1)

n = 6.2/-10.4=0.5962

Step-by-step explanation:

What is the value of n in the equation. we would make n the subject formula -1.2(2n+4)+6=-9+4(2n+1)

Opening the brackets,

-1.2×2n -1.2×4 + 6= -9 +4×2n + 4×1

-2.4n -4.8 +6 = -9 +8n + 4

-2.4n -4.8 +6 = -9 + 4 + 8n= -5+8n

Collecting like terms

-2.4n-8n = -5+4.8-6

-10.4n =-6.2

n = -6.2/-10.4= 0.5962

Let's check, put n= 0.5962 in the equation

-2.4n -4.8 +6 = -9 +8n + 4

Lefthand side

-2.4×0.5962-4.8+6= -0.230

Right hand side

-9+ 8× 0.5962 +4

=-9 +4.7696 +4

=0.230

Right hand side = left hand side

sorry, i can't understand your question. will later if you describe more clearly!
