3x+y=19

y=19-3x and y=x+3, at a solution both x and y are equal so we can say y=y:

19-3x=x+3

19-4x=3

-4x=-16

x=4, and since y=x+3

y=7 so the solution is the point:

(4,7)

Answer:

Lemme explain rq.

If a number has a fractional exponent, that bottom part of the fraction goes the to root side when it is turned into a root.

Step-by-step explanation:

For example, 4 to the power of 2/3 becomes cube root of 4 to the power of 2.

When an exponent to a number also has a power

For example:

4 to the power of 2 to the power of 3

$(4^{2} )^{3} = 4^{2 * 3}$

So B because B is the only one where the two powers are multiplied.
