What is the solution to this equation?<br> x/-4=8

guapka [62]

X=32

Explanation:
When you change sides, if in the left side you are multiplying, when you transfer it to right side you divide. Same thing should be done for addition subtraction.

So /-4 was division and negative number

When we transfered it, it became positive multiplication number

Harriet has some five dollar bills and some one dollar bills She has 20 bills. The value of the bills is $72 write and solve a s

boyakko [2]

So let's say
x=number of five dollare bills
y=number of 1 dolar bills

20 bills total
x+y=20

totla is 72 monies
72=5 times x+1 times y=5x+1y=5x+y
solve

x+y=20
5x+y=72
from here you could do 2 things: go to option 1 (longer) or option 2 (shorter)

1.

x+y=20
subtract x from both sides
y=20-x

5x+y=72
subtract 5x from boths ides
y=72-5x
subsitute

y=20-x=y=72-5x
20-x=72-5x
add 5x to both sides
20+4x=72
subtract 20 from both sides
4x=52
divide both sides by 4
x=13

subsitute
x+y=20
13+y=20
subtract 13
y=7

2.

another way is when you got 5x+y=72 and x+y=20
you negative the second equaiton and add to th efirst
I know it sounds like voodo at first but it works
-(x+y=20)=-x-y=-20
add

5x+y=72
<u>-x-y=-20 +</u>
4x+0y=52
4x=52
divide both sides by 4
x=13

subsitute
x+y=20
13+y=20
subtract 13
y=7

If p + 9 = 25 and p = q, then q + 9 = 25.

Evgesh-ka [11]

P and q both equal 16. This is because, 25 - 9 = 16.
