Respuesta :

t = Tom's weight
c = Carl's weight

we know that twice of Carl's weight equals Tom's weight + 20 pounds so
2c = t+20
and we know that Tom's weight + Carl's weight = 340
t+c = 340

then from there you can solve using substitution or elimination

Tom’s weight is 220 pounds and Carl's weight is 120 pounds if together tom and carl weigh 340 pounds.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Tom’s weight is 20 pounds less than twice carl’s weight.

Let x be Tom's weight and y be Carl's weight.

x = 2y - 20

x + y = 340

After solving the above equation by the substitution method:

2y-20+y=340

y = 120 pounds

x = 220 pounds

Thus, Tom’s weight is 220 pounds and Carl's weight is 120 pounds if together tom and carl weigh 340 pounds.
