Identifying Systems of Equations
Claro, podemos resolver este sistema de ecuaciones. En la imagen que proporcionaste, veo una ecuación lineal y otra ecuación que no está completamente visible, pero parece tratarse de un sistema de ecuaciones. Primero necesito la ecuación completa del sistema. ¿Podrías proporcionar la segunda ecuación que falta?
Solving Equations with Elimination of Variables
To solve for x, we have these two equations from the image without the y variables: 1) -2x + 4y = 15 2) -12x - 4y = -8 Adding these two equations together will eliminate the y terms since they have opposite coefficients: -2x + 4y = 15 -12x - 4y = -8 ---------------- -14x = 7 Now, we solve for x by dividing both sides of this equation by -14: -14x / -14 = 7 / -14 x = -1/2 Therefore, the value of x is -1/2, which corresponds to option A: -1/2.
