4.2x - 1.4y = 2.1    |multiply both sides by 10

42x - 14y = 21    |subtract 42x from both sides

-14y = 21 - 42x    |change signs

14y = 42x - 21    |divide both sides by 14

y = 3x - 1.5

What’s the answer to number 19??
Igoryamba

The answer equals 6.

Since 3 3/4 equals 15/4, when you divide you have to switch the numbers in the  divisor and then you turn the equation into multiplication.

So then it will be 15/4 x 4/3.

15 x 4 = 60

4 x 3 = 12 so the answer is 60/12. But you have to simplify so half of 60/12 is 30/6 and then half of 30/6 is 15/3 then you have to pick the gcf of 3 and 15 which is 3.

15 divided by 3 equals 5.

3 divided by 3 equals 1 so 5/1 equals 5

Hope this helps! ;)
