19. 2=5(5z-2)-9(3z-2)

Step-by-step explanation:

2 = 5(5z - 2) - 9(3z - 2)

2 = 5*5z - 5*2 - 9 * 3z - 9 *(-2)

2 = 25z - 10 - 27z + 18

25z - 27z  + 18 - 10 = 2

25z - 27z = 2 + 10 - 18

-2z = -6

z = -6/-2

z = 3

Step-by-step explanation:

Simplify,

Combine like terms,

Flip the equation,

Subsract 8 by both sides

Divide both sides by - 2,

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.
