18. Gerry is three years older than Terry. In six years the sum of their ages will be 99.
How old are they now?

Please Help!!!

Gerry will have 96 I think and Terry will have 93 don't be to sure I really don't know.

Step-by-step explanation:

99 - 6 = 93 + 3 = 96

99 - 6 = 93

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
