Solve the system by substitution y=6x and 7x-8y=-41

x = 1

y = 6

Step-by-step explanation:

y = 6x   (I)

7x - 8y = -41   (II)

Substitute y =6x in equation (II)

7x - 8*(6x) = -41

7x - 48x    = -41   {Combine like terms}

     -41x = -41

          x = -41/-41

x = 1

Plug in x = 1 in equation (I)

y = 6*1

y = 6

answer: the answer is 127 degrees

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 !
