What is the first step to solve the following system of equations using substitution?

Akimi4 [234]

Answer:

Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for x

Thus, option A) is true.

The solution to the system of equations be:

$x = 4, y = 5$

Step-by-step explanation:

It is important to remember that when we solve the system of equations, the first step we need to do is to solve one of the equations for one of the variables.

Given the system of equations

$x - y = -1$

$2x - y = 3$

Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for x

$x-y=-1$

Add y to both sides

$x-y+y=-1+y$

$x=-1+y$

Thus, option A) is true.

<u>NOW LET US SOLVE THE REMAINING PORTION</u>

$\mathrm{Subsititute\:}x=-1+y$ to solve for y

$\begin{bmatrix}2\left(-1+y\right)-y=3\end{bmatrix}$

$-2+y=3$

$y=5$

For x = -1 + y

substitute y = 5

$x=-1+5$

$x=4$

Thus, the solution to the system of equations be:

$x = 4, y = 5$

Can someone help me on this

Morgarella [4.7K]

Answer:

m∠A = 91°

Step-by-step explanation:

∠A ≅ ∠B (Vertical Angle Theorem). This means that the two angles will have the same measurements.

Note that a straight line = 180° (Definition of a Straight Line).

Find the value of m∠B.

180 - 47 - 42 = m∠B

m∠B = 180 - (89)

m∠B = 91°

Remember that ∠B & ∠A are vertical angles, so they will have the same measurement.

m∠A = 91°

Find the value of the expression x3−y3+x2+y2+3 by substituting x=−2 and y=1.

vaieri [72.5K]

$\\ \sf\dashrightarrow x^3-y^3+x^2+y^2+3$

$\\ \sf\dashrightarrow (-2)^3-(1)^3+(-2)^2+(1)^2+3$

$\\ \sf\dashrightarrow -8-1+4+1+3$

$\\ \sf\dashrightarrow -9+8$

$\\ \sf\dashrightarrow -1$
