Yo I’m finna give u the link tho this answer https://socratic.org/questions/how-do-you-solve-p-2l-2w-for-l#581467
That’s as low as it goes So that’s ur answer
14/37
The value of x is
-4x + 8 = 42
-4x = 42 -8
-4x = 34
x = -8,5
Cancel something
we cancel x's
multiply 1st equation by 5 and 2nd by 7 and add them
-35x-30y=-5
<u>35x-28y=7 +</u>
0x-58y=2
-58y=2
divide both sides by -58
y=-1/29
sub back
5x-4(-1/29)=1
5x+4/29=1
minus 4/29 from both sides
note, 1=29/29
5x=25/29
divide bot sides by 5 (or times 1/5)
x=5/29
(5/29,-1/29)
40/100=0.4 and 72/0.4=180
so the answer is 180
