When solving the system of equations 3x−3y=1 and −2x+4y=2 algebraically, a good first step is to:
bearhunter [10]

Answer:

A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.

Step-by-step explanation:

Given

3x - 3y = 1

-2x+ 4y = 2

Required

A good first step

A good first step is to eliminate x and this is done as follows:

Multiply 3x - 3y = 1 by 2 (gotten from coefficient of x in the second equation)

Multiply -2x+ 4y = 2 by 3 (gotten from coefficient of x in the first equation)

This gives:

6x - 6y = 2

-6x + 12y = 6

Add both equations

6x - 6x - 6y + 12y = 2 + 6

6y = 8

y = \frac{4}{3}

<em>Hence (a), is true</em>
