Question

y = -2.8x + 150.4
y = 14.4x + 102.8 
 can someone solve and show steps? i already did i just want to check my work

dallaslifebaby01 · Answer

my solution 
-2.8x+150.4 = 14.4x +102.8
150.4 = 14.4x +2.8 + 102.8
150.4 – 102.8 = 17.2x
47.6 = 17.2x
x=47.6/17.2

amorfide · Answer

-2.8x+150.4 = 14.4x +102.8 correct

150.4 = 14.4x +2.8 + 102.8 you forgot to put x after the 2.8, so this line should be
150.4 = 14.4x +2.8x + 102.8 

150.4 – 102.8 = 17.2x correct
47.6 = 17.2x correct
x=47.6/17.2 correct

is that all i would need to solve? I'm not missing anything? and its completely solved?

amorfide · Answer

you cuold probably use a calculator to get a decimal answer

amorfide · Answer

you would then use that value of x, substitute it into one of the two given equations
and work out a y value

okay thanks

amorfide · Answer

y = 14.4x + 102.8 
y=14.4(47.6/17.2)+102.8

amorfide · Answer

then you have both values then it is solved
