Answer:
cost to make paper signs = $1
cost to make laminated signs = $2
Step-by-step explanation:
Let
x = cost to make paper signs
y = cost to make laminated signs
8x + 2y = 12 (1)
10x + 10y = 30 (2)
Multiply (1) by 5
40x + 10y = 60 (3)
10x + 10y = 30 (2)
Subtract (2) from (3) to solve for x
40x - 10x = 60 - 30
30x = 30
x = 30/30
x = $1
Substitute x = 1 into (1)
8x + 2y = 12
8(1) + 2y = 12
8 + 2y = 12
2y = 12 - 8
2y = 4
y = 4/2
y = $2
cost to make paper signs = $1
cost to make laminated signs = $2
4 + -6 = -2
Hope that helps? Sorry if it doesn’t...

I did this one before and I still remember this problem
Answer:
18x+y=-52
Step-by-step explanation:
we all know and love(being 100% sarcastic here)the standard form as
ax+by=c
y=-9(x+3)*2+2----This is weird and not so nice
so lets make it nice by distributing the 9::::
y=(-9x-27)2+2
and now the 2:
y=-18x-54+2
y=-18x-52
oops this is NOT in S.F we got to switch the -52 and y
52=-18x-y
-18 cant be neg. so we have to divide by -1 on both sides
-52=18x+y
18x+y=-52
HOPE THIS HELPS
