Answer: 9
Step-by-step explanation: You can start by setting this up as an equation, where X is Brooke’s age.
X + 2(x)+ 3 = 30
The 2(X) + 3 signifies the part of the problems identifying that Mia is twice her sisters age plus 3 years.
Combine x’s
3x + 3 = 30
Subtract 3 from both sides to isolate the x term
3x= 27
Divide both sides by 3 to reduce to a single x
X= 9 , which is brooke’s age
For the answer to the question above, a system of equations has no solution when the lines representing the equation are parallel but do not coincide. For two lines to be parallel, the must have the same gradient i.e. coefficient of x when y is made the subject of formula must be equal.
If one of the equations is
y = 8x + 7,
then the other equation will be
y = 8x - 7
