Answer:
Multiply both sides of the equation by 1/3
Step-by-step explanation:
3x^2+18x=21
The first step is to get the x term with a coefficient of 1, so divide by 3 on both sides of the equation
This is the same as multiplying by 1/3
1/3 * (3x^2+18x)=21*1/3
x^2 +6x = 7
You have to start with thy x and the division than the minus and the plus
Total amount in payments = 48 + 47.80 + 47.60 + 47.40 + 47.20 + 47.01 = 285.01
