Question 150800: Solve the system of linear equations by the substitution method.
y = -4/3x
4x + 2y = 3/4

y = -4/3x
4x + 2y = 3/4
Plug in -4/3x for y
4x + 2(-4/3x)= 3/4
Distribute
*(4)x-(8/3)x=3/4
*(4=12/3, so (4)x= (12/3)x.........(12/3)x-(8/3)x=4/3x)
4/3x=3/4
*Divide both sides by 4/3 to isolate x
4/3x divided by 4/3= 3/4 divided by 4/3
x=9/16
x=9/16
y=-4/3x
y=-4/3(9/16)
y=-3/4
Answer:
x=9/16
y=-3/4
