Answer:

Multiply each entry by 2!

Step-by-step explanation:

Multiplying a matrix by a constant means to multiply each entry by that constant.

According to that, 2A would be the result of each entry being multiplied by 2.

That is equal to $$ 2A = \begin{pmatrix}2(4) & 2(9) \\2(13) & 2(5) \\\end{pmatrix}$

$$ \implies 2A = \begin{pmatrix}8 & 18 \\26 & 10 \\\end{pmatrix}$

Hence, the answer.

Y=2x and x+3y=-14 substitution to solve each system of equations

Sergeeva-Olga [200]

You can use the substitution method.
You substitute the first equation to the second equation to get the value of x.
x + 3y = -14
x + 3(2x) = -14
x + 6x = -14
7x = -14
x = -14/7 = -2

Substitute the value of x to the first equation.
y = 2(-2) = 4
