Question

x−1=74x−1+40+y−2+180
x=75 and y=68? Need steps am confused

Answer 1

do you have to find the value of a specific variable?

Answer 2

@mmk1

Answer 3

yes x and y
x=75
y=68 but confused with steps

Answer 4

hold on

Answer 5

180=z+13+Y
SAME TYPE-NEED TO SOLVE FOR Z

Answer 6

x−1=74x−1+40+y−2+180
First things first....(combine like terms)
x−1=74x−139+y
-74x-1=-139 + y
+1 1
----------------
-74x=-138 + y
What did I do wrong?????.........
Let's see show me how you got X AND Y

Answer 7

The second one is:
180=z+13+Y
-13 -13
------------
167=z + Y
- Y - Y
----------
167 - Y = z or z = -Y + 167

Answer 8

That's how u solve for Z

Answer 9

OK THANK YOU!

Answer 10

np how bout the first one?

Answer 11

BACK TO THE FIRST ONE
-74x=-138+y
-74(75)=-138+68
-5550=-70???

Answer 12

at first like, you solve it and show me r work

Answer 13

x-1=74x-1+40+y-2+18
x=74x+37+18
x=74x+55


I am stuck

Answer 14

@phi @ganeshie8 can u plz help mmk1 with this

Answer 15

if you have 2 unknowns then (to solve) you need 2 separate equations

Answer 16

Your equation (if the above equation as mentioned in the question is correct) will become like this =>
73x + 218 + y = 0
Now 2 things can be inferred :
1) We need another equation to solve for values of x and y.
2) The nature for the ans. for x and y can never be simultaneously positive. One of them will surely be a negative no.
