Question 1 of 10

Use the matrix tool to solve the system of equations. Choose the correct
ordered pair.
3x - 4y= -6
2x-5y=-11

Answer 1

x = 2 ; y= 3

Explanation:

3x = 4y-6

3/3 x = 4/3 y - 6/3

x = 4/3 y - 2

2(4/3y-2) - 5y = -11

8/3 y - 4 - 5y = -11

(8-15)y / 3 = -11 + 4

-7/3 y = -7

-7/3 y * -3/7 = -7 * -3/7

y = 3

x = 4/3 * 3 -2

x = 4-2

x = 2
