Solve the following system of equations using the elimination method. 5x – 5y = 10 6x – 4y = 4
tresset_1 [31]

Answer:

x=-2,y=-4

Step-by-step explanation:

By dividing to lowest terms

5x – 5y = 10= x-y=2.......(1)

6x – 4y = 4=3x-2y=2........(2)

By elimination method

Multiply equation (1) by 3 so as to correspond with equation (2)

3(x-y)=3(2)

3x-3y=6..........(3)

Multiply equation (2) by 1 so as to correspond with equation (1)

1(3x-2y)=1(2)

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

Then equation (3)-equation (4)

(3x-3y=6)

-

(3x-2y=2)

__________

-y=4

y=-4

Substitute y=-4 into equation(1)

x-(-4)=2

x+4=2

x=-2

Therefore x=-2,y=-4

gladu [14]

Answer:

  • 28 more strokes

Step-by-step explanation:

42 strokes = 3/5 of line

<u>Divide both by 3/5</u>

  • 42 : 3/5 strokes = 1 line
  • 42*5/3 strokes = 1 line
  • 70  strokes  = 1 line

70 - 42 = 28 more strokes to complete the line
