i don't care if you answer one, a few or all of them. but i need with this fast

(a)write the equation for a line 1 in slope-intercept form.

(b) right equation for line 2 in slope-intercept form

(c) is the system or creations consistent independent, coincident, or inconsistent? explain.

(d) what is the solution to the system? use the substitution method.

the answer is 21%.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
