Question

Solve the equation by elimination

Answer 1

Answer:

(1,-7)

Step-by-step explanation:

y= -9x + 2.............equn(1)

y= -3x - 4..........................(2)

subtract equation (1) from equn. (2)

0= -6x + 6

subtract 6 from both sides

0-6= -6x + 6-6

-6 = -6x

divide via by -6

-6/-6 = -6x/-6

x=1

to solve for y, put x in any equation

equation (1)

y=-9x+2

y=-9(1)+2

y=-9+2

y= -7
