Question

calcule o número z sabendo que ele vale o dobro de y , somando com o triplo de x

Answer 1

Z = 2Y+3X

Simplifying Z = 2y + -3x
Reorder the terms: Z = -3x + 2y
Solving Z = -3x + 2y
Solving for variable 'Z'.
Move all terms containing Z to the left, all other terms to the right.
Simplifying Z = -3x + 2y
