DETERMINE X

a)2x+3=x+4
b) 9x+9+3x=15
c)16x-1=12x+3
d)3x-2=4x+9

Answer 1

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

b) 9x+9+3x=15
9x + 3x = 15 - 9
12x= 6
x = 6/12
x = 1/2

c)16x-1=12x+3
16x-12x= 3 + 1
4x = 4
x= 4/4
x= 1

d)3x-2=4x+9
3x-4x =9+2
-x=11     .(-1)
x = -11

Answer 2

a)2x+3=x+4
2x-x=4-3
x=1
b)9x+9+3x=15
9x+3x=15-9
12x=6
x=6/12
x=0,5
c)16x-1=12x+3
16x-12x=3+1
4x=4
x=4/4
x=1
d)3x-2=4x+9
3x-4x=9+2
-x=11
x=11/-1
x=-11
