Can someone help me with this problem? {18 points}

Square = 2

Triangle = 3

Circle = 1

= 7

Step-by-step explanation:

1 square = 2

2 × 2 × 2 = 8

1 triangle = 3

2 × 3 × 3 × 3 = 54

1 circle = 1

2 × 3 × 1 × 1 = 6

1 + 2 × 3 = 7

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
