Answer:
n = -101/90
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
(1+9n) (10) = −91
(1) (10) + (9n) (10) = −91 (Distribute)
10 + 90n = −91
90n + 10 = −91
Step 2: Subtract 10 from both sides.
90n + 10 − 10 = −91 − 10
90n = −101
Step 3: Divide both sides by 90.
90n/90 = −101/90
n = −101/90
