Question

Solve each system by elimination. -6x + 5y= 1 6x+4y=-10

Answer 1

(-1,-1)

Explanation:

Given the system of equation

-6x + 5y= 1 ..... 1

6x+4y=-10 ..... 2

Adding both equations to eliminate x;

0 + 5y + 4y = 1 - 10

9y = -9

y = -9/9

y = -1

Substitute y = -1 into 2

From 2; 6x+4y=-10

6x+4(-1)=-10

6x-4=-10

6x = -10+4

6x = -6

x = -6/6

\x = -1

Hence the required solution (x, y) is (-1,-1)
