I can help you with this

anonymous · Answer

Ok

hero · Answer

1. Solve both equations for y: 

$$y = \frac{1-5x}{-3}$$
$$y = \frac{2-7x}{-4}$$

Next, set y = y: 

$$\frac{1-5x}{-3} = \frac{2-7x}{-4}$$

hero · Answer

Cross Multiply, then isolate x

hero · Answer

-4(1-5x)=-3(2-7x)

-4+20x = -6+21x

x = 2

hero · Answer

y = 3
