Solve simultaneous equation by substitution method
y-4x=6
2y-3x=4

Step-by-step explanation:

y-4x=6

y=6+4x, using this value in 2y-3x=4 gives

2(6+4x)-3x=4

12+8x-3x=4

5x+12=4

5x=-8

x= -8/5= -1.6, making y=6+4x become

y=6+4(-1.6)

y= -0.4, so the solution is the point

(-1.6, -0.4)

(x, y)→(x − 8, y − 7)
