Answer: Age of Lin is 12
Solution:
Let X= age of Maya
(X/2)+4= age of Adrian
((X/2)+4)-7= age of Lin
X+(X/2)+4+((X/2)+4-7)=61
X+.5X+4+.5X+4-7=61
2X+4+4-7=61
2x=61-8+7
2X=60
X=30 age of Maya
19= age of Adrian
Age of Lin is
=((X/2)+4)-7
=15+4-7
=12

Part A:5=2x^2-x^2+13
5=x^2+13
0=x^2+13-5
0=x^2+8
Part B:5=2x^3-x^3+13
5=x^3+13
0=x^3+13-5
0=x^3+8
Linear equations are:
Non-linear equations are:
Step-by-step explanation:
Lets define linear and non-linear first.
Linear equation is that equation whose degree is one. Degree is the highest power of a variable in an expression or equation.
Similarly, an equation with degree greater than 2 are called non-linear equation
In the given equations,
=> Degree: 3
=> Degree: 1
=> Degree: 2
=> Degree:1
=> Degree:2
Hence,
Linear equations are:
Non-linear equations are:
