8 0

15+8x=2x+7-5x

Subtract 8x from both sides.
15=2x+7-5x-8x

Combine like terms.
15=-11x+7

Subtract 7 from both sides.
8=-11x

Divide -11 from both sides.
.73=x

Step-by-step explanation:

Thursday:

The ratio of adult cat to kitten at a pet care center on Thursday was 4:3.

Number of adult cats = 4x

Number of kitten cats = 3x

There were 12 kittens, then

$3x=12\\ \\x=\dfrac{12}{3}\\ \\x=4\\ \\4x=4\cdot 4=16$

There were 16 adult cats

Tuesday:

17 adult cats were at the pet care center.
