Determine three consecutive whole numbers where two times the smallest number is added to the middle number and then added to three times the largest number to total 73
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Determine three consecutive whole numbers where two times the smallest number is added to the middle number and then added to three times the largest number to total 73
Let a is the first number.
So three consecutive whole numbers are a, a+1, and a+2.
Two times the smallest number is added to the middle number and then added to three times the largest number to total 73. So,
2a+(a+1)+3(a+2)=73
