6x7=42 42=5=47 so 6x7+5=47
5x-1+2= 5x+1
5x - 1 = 24 5x - 1 + 1 = 24 + 1 5x = 25 5x/5 = 25/5 x = 5

5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
To find 6x7 using 3x7, you can simply double the result of 3x7. This is because multiplication is distributive over addition, meaning that multiplying a number by a sum is the same as multiplying the number by each addend and then adding the products. In this case, 6x7 can be thought of as (3+3)x7, which equals 3x7 + 3x7, or 21 + 21, which equals 42.
The property states that the order of the addend or factor does not change the sum or product. 2+3=5 3+2=5 6x7=42 7x6=42 5x(7+6)=5x(6+7)
4 + 5x = 1 5x = 1 - 4 5x = -3 x = -3/5 x = -0.6
