    21,882+4,9 n=4,2 (1,8 n +3,69) Distribute the 4,2 to each term inside the parentheses.4,2 × 1,8 n=7,56 n, and 4,2 × 3,69=15,49821,882+4,9 n=7,56 n +15,498Subtract 15,498 from each side.21,882 — 15,498=6,3846,384+4,9 n=7,56 nSubtract 4,9 n from each side so that we have the variable alone.7,56 n — 4,9 n=2,66 n 6,384=2,66 nDivide each side by 2,66 to find the value of n.6,384 ÷ 2,66=2,4 n=2,4
