Answer:

$(5, \: - 2)$

Step-by-step explanation:

$x + 3y = - 1 \\ 2x + 2y = 6 \\ solve \: the \: equation \\ \\ x = - 1 - 3y \\ 2x + 2y = 6 \\ substitute \: the \: value \: of \: x \: into \: an \\ equation. \\ \\ 2( - 1 - 3y) + 2y = 6 \\ distribute \\ \\ - 2 - 6y + 2y = 6 \\ add \: - 6y \: to \: 2y \\ \\ - 2 - 4y = 6 \\ add \: 2 \: from \: both \: sides \\ \\ - 2y = 8 \\ divide \: both \: sides \: by \: 2 \\ \\ y = - 2 \\ substitute \: the \: value \: of \: y \: into \: an \\ equation. \\ \\ x = - 1 - 3( - 2) \\ distribute \\ \\ - 1 + 6 \\ add \: - 1 \: to \: 6 \\ \\ x = 5 \\ \\ (5, - 2)$

Aneli [31]

Answer: For every 7 plants in Coco's garden, there are 2 pumpkin plants.

since we have given that

Number of tomato plants = 8

Number of pepper plants = 4

Number of squash plants = 3

Number of pumpkin plants = 6

Total number of plants = 8+4+3+6=21

So, every 21 plants in Coco's garden, there are 6 pumpkin plants ,

So, we have asked to find for every 7 plants in Coco's garden , which type has 2 plants,

so, we did

So, according to this pattern,

if we multiply 2 with 3 i.e.

So, it will only be pumpkin plants,

So, For every 7 plants in Coco's garden, there are 2 pumpkin plants .
