You can put this solution on YOUR website! 2[7-5(1-n)] +8n = 16+3[6(n+1)+3n]
.
Use P E M D A S,,, Parenthesis, Exponents, Multiply/Divide.lt to rt
,,,Add/Subtract,,lt to rt,,,
.
.
2[7-5+5n] +8n = 16 + 3[6n +6 +3n]
.
2[2+5n]+8n = 16 + 3[ 9n+6]
.
4+10n+8n = 16 +27n +18
.
4+18n = 34 +27n
.
-9n = 30
.
n=-30/9 = -3 1/3
.
check,,,subst into original
.
2[7-5(1-(-3.3))] +8(-3.3) = 16 +3[6(-3.3) +6 +3(-3.3) ]
.
-56 = -56,,,,ok
