Answer:

B (4, 9)

Step-by-step explanation:

Isolate one of the variable on the first equation

5 = -x + y

turn to

x = y - 5

Then insert this into the second equation

3 = 3(y - 5) - y

Simplify-

3 = 3y - 15 - y

3 = 2y - 15

Add 15 to both sides

18 = 2y

Divide by 2

9 = y

knowing y = 9 you can assume that -

(x, 9)

This means the only possible answer is B

Solve the system of equations. If the system has no solution, say that it is inconsistent. Graph the lines of the system.
Romashka-Z-Leto [24]

Answer:

The solution to the system of the equations will be:

x=3,\:y=1

Step-by-step explanation:

Given the system of the equations

x+y=4

x-y=2

solving the system of the equations

\begin{bmatrix}x+y=4\\ x-y=2\end{bmatrix}

x-y=2

-

\underline{x+y=4}

-2y=-2

solving

-2y=-2

Divide both sides by -2

\frac{-2y}{-2}=\frac{-2}{-2}

y=1

\mathrm{For\:}x+y=4\mathrm{\:plug\:in\:}y=1

x+1=4

x=3

Therefore, the solution to the system of the equations will be:

x=3,\:y=1

m_a_m_a [10]

Answer:

5/6

Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
