18x+5=2 (-3x)^2+5
18x+5=36x^2+5
18x-36x^2=0
18x(1-2x)=0 (1-2x)=0 or 18x=0 -2x=-1 x=2 Answer: 2 or 0
Answer:
y=⅓x-3
Step-by-step explanation:
y--2=⅓(x-3)
y+2=⅓x-1
y=⅓x-1-2
y=⅓x-3
Answer:
y= 1/2, x=1/2
Step-by-step explanation:
1st equation:
2x/3 + 3y/4 = 17/24 ... multiply it with 6
4x + 18y/4 =17/4
2nd equation:
4x/3 + 5y/3 = 3/2 .....multiply it with 3
(-) 4x + 5y = 9/2
using elimination method
4x + 5y = 9/2
4x + 18y/4 =17/4
......................................... <em> x cancel out's</em>
y/2 =1/4
y= 1/2
so x, 4x + 5y =9/2
x = (9/2 -5y)/4
x=(9/2 -5(1/2)/4
=1/2
