Solve the equation below and find the variation constant, k
Find x when y= 141 and z = 19, if y varies jointly as x
and z, and y = 61 and x = 4 when z = 20.*
*Round your answer to the nearest thousandth, if necessary.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
