300x + 300 x plus StartFraction 500 over 7 EndFraction left-parenthesis 87.5 right-parenthesis equals 10,000.y = 10000

x = 12.5

Step-by-step explanation:

The correct question can be found in the attachment

300x + 500/7y = 10,000

Find x if y = 87.5

Substitute y = 87.5 into the equation

300x + 500/7(87.5) = 10,000

300x + 43,750/7 = 10,000

300x + 6,250 = 10,000

Subtract 6,250 from both sides

300x + 6,250 - 6,250 = 10,000 - 6,250

300x = 3,750

Divide both sides by 300

x = 3,750/300

= 12.5

x = 12.5 when y = 87.5

step-by-step explanation:

i am not sure sorry : c

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
