Question

e) 0,5x-9=15
f) 4x+3=-19
g) 5x+2=2x-1

Answer 1

e) 0,5x - 9 = 15
0,5x = 24
x = 48

f) 4x + 3 = -19
4x = -22
x = -5,5

g) 5x + 2 = 2x - 1
5x - 2x = -1 -2
3x = -3
x = -1

Answer 2

e) 0,5x-9=15
0,5x=15+9
0,5x=24
x=24/0,5
x=48
f) 4x+3=-19
4x=-19-3
4x=-22
x=-22/4
x=-5,5
g) 5x+2=2x-1
5x-2x=-1-2
3x=-3
x=-3/3
x=-1
