Question 9 of 10

A system of two equations is shown below. What will you need to multiply the
top equation by in order to solve this system using the elimination method?
X +2y = 11
6X + 4y = 34
A. 6
• B. -2
C. 2
( D. -4

Answer 1

by 6

Explanation:

Isolate x for x + 2y= 11: x= 11- 2y

Substitute x =11 -2y

6(11 - 2y) + 4y = 34|

Simplify

[66 -8y= 34]

Isolate y for 66 - 8y= 34: y =4

For x = 11 - 2y

Substitute y = 4

X= 11-2 x 4

Simplify

X=3

The solutions to the system of equations are:

X=3,y=4
