2y=1/2x+10
divide by two
y=1/4x+5
Answer:
Step-by-step explanation:
product: -18x4 + 15x2 - 15x
the simplification just ends up being the original equation.
Step-by-step explanation:
3x-4y=13
y=-3x-7
3x-4(-3x-7)=13
3x+12x+28=13
15x=-15
x= -1
y= -3x-7 = 3-7= -4
( -1, -4)
Answer:
34
Step-by-step explanation:
5x+10=180
5x=170
