Method 1 :

replace x and y by their value 1 and 3

3 = 4(1) - 1 = 4-1 = 3

2(1) + 3 = 2 + 3 = 5

correct

Method 2 :

y = 4x - 1

2x + y = 5

y = 4x - 1

y = -2x + 5

y - y = 4x - 1 - ( -2x + 5 )

0 = 4x - 1 + 2x - 5

6x - 6 = 0

6x = 6

x = 6/6 = 1

y = 4x - 1

y = 4(1) - 1

y = 3

correct

Draw a model to represent the product 41×16

svlad2 [7]

41×16 is 656 because 1×6 is 6. 6×4 is 24. 1×1 is 1. 1×4 is 4. The numbers left are 246 ( 1×6 + 6×4 ), and 41 ( 1×1 + 1×4 ). All together, the answer is 656. Enjoy! :)
