What is the first step to take when solving this linear system of equations by the addition-subtraction method? 2x + 4y = 3 x +

Free_Kalibri [48]

The right answer is Option D.

Step-by-step explanation:

Given equations are;

2x+4y=3 Eqn 1

x+3y=13 Eqn 2

When we use subtraction-addition method, we make one of the variables same with opposite signs so that only one variable remains after addition or subtraction.

In the given problem, we will multiply Eqn 2 with "-2" so that the x variables become equal and then we can add both the equations and solve for y.

Therefore,

The first step will be to multiply the second equation by -2 to solve the linear system of equations.

The right answer is Option D.

Solve for x. x−1/4=3/8

valentinak56 [21]

x=5/8 is the correct answer. First you had to simplify from both sides of equation, and it gave us, $x+\frac{-1}{4}=\frac{3}{8}$ . Then you add 1/4 from both sides of equation, and it gave us, $x+\frac{-1}{4}+ \frac{1}{4}= \frac{3}{8}+ \frac{1}{4}$ . And it gave us the answer is x=5/8 is the final answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
