I need answers whoever give answers I will give brainliest this is just part one btw

P: x + 2 = 9

   x = 7 # Subtract 2 from both sides

E: q - 5 = 12

    q = 17 # Add 5 to both sides

H: 6 + m = 27

    m = 21 # Subtract 6 from both sides

Y: t - 14 = -3

   t = 11 # Add 14 to both sides

J: u - 7.5 = 2.4

   u = 9.9 # Add 7.5 to both sides

I: n + 7 = -20

  n = -27 # Subtract 7 to both sides

G: d - 1 = -16

   d = -15 # Add 1 to both sides

A: b - 40 = -25

   b = 15 # Add 40 to both sides

M: 18 + w = 7

    w = -11 # Subtract 18 from both sides

L: k + 8.3

   k = 11.5 # Subtract 8.3 from both sides.

P.x+2=9

x=9-2

x=7

L.n+7= -20

n=-20-7

n=-27

E.q- 5 = 12

q=12+5

q=17

G.d-1=-16

d=-16+1

d=-15

H. 6 + m = 27

m=27-6

m=21

A. b - 40 = -25

b=-25+40

b=15

Y. t - 14 = -3

t=-3+14

t=11

M. 18 + w = 7

w=7-18

w=-11

J.u - 7.5 = 2.4

u=2.4+7.5

u=9.9

L.K+ 8.3 = 19.8

k=19.8-8.3

k=11.5

4

step-by-step explanation:

b.an increase in a causes b to decrease
