Step-by-step explanation:

Step 1: Substitute -x+18 for y in y=8x:

-x+18=8x Add X to both sides

9x=18 Divide 9 by both sides

x=2

y=8(2)Plug in the new value for x(which is 2) into one of the equations

y=16

Answer:

(2,16)

Step-by-step explanation:

y=-x+18

y=8x

8x=-x+18

8x+x=9x

9x=18

9x/9=x

18/9=2

x=2

y=8(2)

y=16

Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs. If x represents the number of 3 lb

olga2289 [7]

Answer:

3x = 50 - 10y

Step-by-step explanation:

Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,

So, total weight of 3 lb weights = 3x

And, the weight of 10 lb weights = 10y

Total weight of all his weights = 3x + 10y

According to the question,

Total weight = 50 lb,

⇒ 3x + 10y = 50

Or 3x = 50 - 10y

Which is the required equation.

Second option is correct.
