解这个方程,分配律should be applied to the first part of the equation, and the numbers in the parentheses should be multiplied by each other.
Example Question #71 :Equations
If Elaine is six years younger than twice Jack's age, and Jack is currently 12, how old is Elaine?
24
36
18
20
32
18
If Elaine is six years younger than twice Jack's age, and Jack is currently 12, how old is Elaine?
We must rewrite this word problem in terms of an equation.
The phrase 'six years younger than twice Jack's age' indicates the algebraic expression
2 x Jack's age – 6
If Jack is currently 12, we can simply plug in this value into our expression to get
2 x 12 – 6
Remember "order of operations"! Multiplication comes before subtraction.
24 – 6 =
18.
Elaine is currently 18 years old.
Example Question #71 :How To Find The Solution To An Equation
Solve for:
Simplify the right side of the equation by adding 120 and 5:
Divide each side by 5:
Take the square root of both sides to isolate:
