Question

Jeannie is 8 years older than her younger sister April. When added together, their ages equal 198. How old is April?

Answer 1

someone please help me :( it seems really simple i just dont know how to write it into a equation

Answer 2

Jeannie - 8 years =age of april

So
j - 8 = a

Jeannie's age + Aprils age = 198

So
j+a=198

So we have two equations
1) j+a=198

and

2) j-8=a

So plug the 2nd into the first for a

j+a=j+j-8=198

2j=206

j=103

so
a=j-8 = 103-8 = 95

April is 95.
