Answer:
Multiply the top equation by -3 and the bottom equation by 2
Step-by-step explanation:
Given <u>system of equations</u>:
To solve the given system of equations by addition, make one of the variables in both equations <u>sum to zero</u>. To do this, the chosen variable must have the <u>same coefficient</u>, but it should be <u>negative</u> in one equation and <u>positive</u> in the other, so that when the two equations are added together, the variable is <u>eliminated</u>.
<u>To eliminate the </u><u>variable y</u>:
Multiply the top equation by -3 to make the coefficient of the y variable 6:
Multiply the bottom equation by 2 to make the coefficient of the y variable -6:
Add the two equations together to <u>eliminate y</u>:
<u>Solve</u> for x:
<u>Substitute</u> the found value of x into one of the equations and <u>solve for y</u>:
