Answer:

Step-by-step explanation:
3x-2y=24......eqi
x+2y=48........eqii
now solving eq i&ii
4x=72
x=72/4
x=18
now putting the value of x in eqii
18+2y=48
2y=48-18
y=30/2
y=15
Answer:
Step-by-step explanation:
<h2> Subtract 0,10 and 12,0 switch it to look like 12,0 and ,10 which i guess is A </h2>
135 + (-136) = 135 - 136

Answer:
x y
0 -1
-1 0
-8 7
Step-by-step explanation:
y = -x - 1
when x = 0, y = -1
when y = 0
0 = -x - 1
x = -1
when x = -8,
y = -(-8) - 1
y = 7
Answer:
-3<x
Step-by-step explanation:
10 < 3x + 19
10 - 19 < 3x
-9 < 3x
-9/3 < x
-3 < x
