Question

Como resolver esta equação x=y
x+3y=28

Answer 1

Simplifying X + -3y = -28 Solving X + -3y = -28 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '3y' to each side of the equation. X + -3y + 3y = -28 + 3y Combine like terms: -3y + 3y = 0 X + 0 = -28 + 3y X = -28 + 3y Simplifying X = -28 + 3y

Answer 2

Se x = y, podemos somar os dois e encontrar z.

4z = 28
z = 7
