Examples od REAL-LIFE MATH SITUATIONS:

My age is twice as you. The sum of our age is 60. How old are we?

let M for my age

Y for your age

A = 2Y

A + Y = 60

2Y + Y = 60

3Y = 60

Y = 60/3

Y = 20 your age

A = 2(20)

A = 40 my age

I paid P40 for 2ballpens and 4 pencils. Each ballp3n cost 3 times more than each pencil. How much was each ballpen and a pencil?

2B + 4P = 40

B = 3P

2B + 4P = 40

2(3P) + 4P = 40

6P + 4P = 40

10P = 40

P = 40/10

P = 4 each pencil cost

B = 3(4)

B = 12 eavh ballpen cost
