Question
if the point (x,3) is on the graph of y=-2x+7, what is the value of x?
Step1: Sustituir y=3 en la ecuación
Sustituimos \( y = 3 \) en la ecuación \( y = -2x + 7 \), obteniendo \( 3 = -2x + 7 \).
Step2: Resolver para x
Restamos 7 de ambos lados: \( 3 - 7 = -2x \), es decir, \( -4 = -2x \). Luego, dividimos ambos lados por -2: \( x = \frac{-4}{-2} = 2 \).
