What is expression?

A sentence with variable and numbers connected by one or more operations is called an expression.

Given that, John has $50 and his sister has $100. John is saving $6 per week and his sister is saving $4 per week.

Amount John have = 6x+50

Amount his sister have = 4x+100

Therefore, establishing the equation, the equations will be equal, since the amount both have is equal, therefore, for equating the expression will find the value x which is the number of week.

6x + 50 = 4x + 100

6x-4x = 100-50

2x = 50

x = 50/2

x = 25

Therefore, they will have equal amounts in 25 weeks.

Hence, the equation for them having the same amount is 6x + 50 = 4x + 100.
