Question

(a) 12t+1-.3)

(b) x/4 + 9 = 7

(d) 2m * 5/2 - 37/2

(e) 8x + 20 = 52

(g) - 2(y * 3) - 7

(h) - 3(4 - x) = 2x + 5

1) 4(5x - 4) + 3(2x - 1) = 7

(k) 7x + 2(x + 2) = 20 - (2x - 5)​

Answer 1

Answer:

b) x/4+9=7

x/4= 7- 9

x/4 = -2

x= -8

e) 8x+20=52

8x= 52-20

8x= 32

x= 4

g) -6y -7=0

y= -7/6

h) -3 (4-x)=2x+5

-12+3x = 2x+5

-17 = -x = x= 17

i) 4 (5x-4)+3 (2x-1)=7

20x -16 +6x -3=7

26x -26=0

x=1

k)7x+ 2 (x+2) = 20-(2x-5)

7x +2x +4 = 20 -2x +5

11x =21

x= 21/11
