When you're dividing by a negative number
1 yogurt = 45p
1p = ? yogurt
1 ÷ 45 = 0.02
5 × 0.02 = 0.10
0.10 yogurt can be bought with 5p (pounds)
The equation has no solution.
<h3>How to solve the equation?</h3>
The equation given is illustrated as:
3x-2y=3 .... i
6x-4y=1 ..... ii
Multiply equation i by 6
Multiply equation ii by 3
18x - 12y = 18
18x - 12y = 3
Subtract the equations.
This will give 0. Therefore, the equations gas no solution.

I think this is more of an opinion question. What someone could solve mentally may not be the same as someone else's.If it were my worksheet, I'd circle all of them but it may be different for you.
At your level, I'd probably circle:
54 - 10
93 - 20
and 39 - 2
