Help plz :)

.

The value of x and y is -2 and 3

step by step explaination:

7x + 3y = -5 be equation 1st and x + y =5 be equation 2nd and multiply equation 2nd by 3 then subtract it .

then we get,

7x + 3y = -5

3x + 3 y= 3

(-). (-). (-)

4x. = -8

x =. - 8/4

x = -2

substitute the value of x in equation in 1

7x +3y = -5

7* (-2) + 3y = -5

-14 + 3y = -5

3y = 14-5

y =9/3

y=3

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 !

what are the statments
