Question

calcule as equações a)x+6=9,b)x-4=5,c)2x+3=x+2,d)x+2=3,e)2x-8=10,f)3x+2=5,g)x+6-2=7,h)2x+3=3x+4

Answer 1

a)x + 6 = 9
x = 3

b) x-4=5
x = 9

c)2x+3 = x+2
x = 2-3
x = -1

d) x+2=3
x = 1

e) 2x -8 = 10
2x = 18
x = 9

f) 3x + 2 = 5
3x = 3
x = 1

g) x+6-2=7
x = 3

h)2x + 3 = 3x +4
-x = 1
x = -1
