Linear equation with a negative rate of change because the balance would decrease by the same amount each day.
try 6x-1....lemme know if it right or wrong... there is a sight called math-way that u can solve problems on...hope that was helpful
Let x be the unknown number of years.
Let C be Chris' age and J be Jenny's age.
Then J+x = 2(C+x)-7
... describes this situation.
4+x = 2(2+x) - 7
4+x = 4 + 2x - 7
x = 2x -7 becomes 7=x
In 7 years, Jenny will be 7 years younger than twice Chris' age.
Check: Is this true? 4+7 = 2(2+7)-7
11 = 18-7, or 11=11 TRUE
combining like terms means to get rid of one factor on both sides of the equation.
