Question

A) 7X+30X-40=-3

B) 3X-2+3X=22

C) 9X+5X-8=34

D) 4X+2Y-5=-3+2Y

E) 56+4X-2=54

F) 93X÷3+4=97

G) 9+4-X=15

H) 8+9-3X= 20

I) 30+4-3X= - 11

J) 7X+2=65

Answer 1

A) 37X = -3 + 40

37X = 37

X = 37/37 = 1

B) 6X = 24

X = 24/6 = 4

C) 14X = 42

x = 42/14 = 3

D) 4X +2Y - 2Y = -3 + 5

4X = 2

X= 2/4 = 0,5

E) 4X + 56 - 2 = 54

4X + 54 = 54

4X = 54 - 54 = 0

F) 93X/3 + 4 = 97

93X/3 = 97 - 4

93x = 93 . 3

93x = 279

x = 279/93 = 3

G) -X = 15 - 13

-X = 2 .(-1)

X = -2

H)-3X = 20 - 17

-3X = 3

X = 3/-3

X = -1

I) 34 -3X = -11

-3X = -45

X = -45/-3 = 15

J) 7x = 65-2 = 63

x = 63/7 = 9
