Given that R=9x+8y find x when y=8 and R=4
Ilya [14]

Answer:

Step-by-step explanation:

R = 9x + 8y

4 = 9x + 8*8

4 = 9x + 64

Subtract 64 from both sides

4 - 64 = 9x + 64 - 64

-60 = 9x

Divide both sides by 9

-60/9 = 9x/9

-20/3 = x

x = -6 2/3

Please help
Firlakuza [10]

Answer:

Step-by-step explanation:

y = -2/3 x       multiply both sides the first equation by 6

6y = -4x                    Add 4x to both sides.

6y + 4x = 0

<u>-9y +4x = - 40   </u>        Subtract the bottom equation

15y =  - 40                 Divide by 15

y = -40/15

y = - 2.7

======================

6y = -4x

6*(-2.67) = -4x

-16 = - 4x

x = - 16/-4

x = 4
