I believe not statistical.
Step-by-step explanation:
Answer:
h = 35
Step-by-step explanation:
Step 1: Write out equation
-37 + h = -2
Step 2: Add 37 to both sides
-37 + 37 + h = -2 + 37
h = 35
Answer:
m=20
Step-by-step explanation:
m-9=11
m-9+9=11+9
m=20
X -2y = 5
X -2y +2y = 5 +2y
X = 5 + 2y
Plug this into first formula.
2X + 3y = -4
2 (5 + 2y) +3y = -4
10 + 4y +3y = -4
10 + 7y = -4
10 -10 + 7y = -4 -10
7y = -14
7y/7 = -14/7
y = -2
Now plug Y back into <span>2x + 3y = -4
2x + 3(-2) = -4
2x -6 = -4
2x -6 +6 = -4 +6
2x = 2
</span>2x/2 = 2/2
x = 1
Check by plugging X & y values in either formula.
2(1) + 3(-2) = -4
2 -6 = -4
-4 = -4
