one number is three more than four time another if the sum of the two number is 23 then find both numbers
zloy xaker [14]
<h3><u>The value of x is 19.</u></h3><h3><u>The value of y is 4.</u></h3>

x = 3 + 4y

x + y = 23

Because we have a value for x we can plug it directly into the second equation.

3 + 4y + y = 23

Subtract 3 from both sides.

4y + y = 20

Combine like terms.

5y = 20

Divide both sides by 5.

y = 4

Plug this value for x back into the original equation.

x = 3 + 4(4)

x = 3 + 16

x = 19

Answer:

E

Solve the equation 5/6×-4=2
lianna [129]
First, you need to add 4 to both sides so you’re left with 5/6x = 6
then, divide 6 by 5/6 to find x
for me personally, it help to write 6 as 6/1
cross multiply so both fractions have the same denominator
6 divided by 5/6 is 36/5 as a mixed number or 7 1/5
