To solve for n start off by adding bn to both sides. an - 4a + 3 + -bn = bn + -bn an - bn - 4a + 3 = 0 Now, add -3 to both sides. an - bn - 4a + 3 + -3 = 0 + -3 an - bn - 4a = -3 Add 4a to both sides. an - bn - 4a + 4a = -3 + 4a an - bn = 4a - 3 Factor out variable n. n(a-b) = 4a - 3 Divide both sides by a - b. a(a-b) / a - b = 4a - 3 / a - b Your final answer is: n = 4a - 3 / a - b
Distribute a an-4a+3=bn minus bn from both sides an-bn-4a+3=0 add 4a to both sides an-bn+3=4a minus 3 from both sides an-bn=4a-3 undistribute n from left side n(a-b)=4a-3 divide both sides by (a-b)
