lianna [129]

Let's say a stands for apples and p for pears
We know that
$p = 1.30$
And

$2a + 7p = 12.70$
In order to know what the cost of an "a" is we have to put the value of the p in the second equation, which means

$2a + 7 \times (1.30) = 12.70$
$2a = 12.70 - 9.10$
$2a = 3.60$
And
$a = 1.80$
The price of per kilo for apples is 1.80
