Which constants can be multiplied by the equations so one variable will be eliminated when the systems are added together?
5x + 13y = 232
12x + 7y = 218
the first equation can be multiplied by –13 and the second equation by 7 to eliminate y.
the first equation can be multiplied by 7 and the second equation by 13 to eliminate y.
the first equation can be multiplied by –12 and the second equation by 5 to eliminate x.
the first equation can be multiplied by 5 and the second equation by 12 to eliminate x.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
