5x+2y=29
x+4y=13
eliminate y's

multiply top equation by -2 and add to first

-10x-4y=-58
x+4y=13 +
-9x+0y=-45

-9x=-45
divide both sides by -9
x=5
sub baack

x+4y=13
5+4y=13
minus 5 both sides
4y=8
divide both sidse by 4
y=2

x=5
y=2
(x,y)
(5,2)

Richard and Teo have a combined age of 37. Richard is 4 years older than twice Teo's age. How old are Richard and Teo?

valkas [14]

Answer:

Teo is 11 years old and Richard is 26 years old.

Step-by-step explanation:

Let R be the age of Richard and T be the age of Teo.

First set up the equations:

The combined age of Teo and Richard is 37:

R+T=37

Richard is four years old than twice Teo's age:

R=2T+4

Then, solve the equations:

Substitute (2) to (1) and solve for T:

(2T+4)+T=37

3T=11

T=11

Solve for R using (2):

R=2(11)+4

R=22+4

R=26

Find all values of c such that 5c - 4 = 7 - 4-c/3

Marina CMI [18]

Hey there!

$5c - 4 = 7 - \dfrac{4 - c}{3} \\ 15c - 12 = 21 - 4 + c \\ 14c = 29 \\ c = 2 \dfrac{1}{14}$

Hope this helps. - M
