Question

Porfa ayudenme a resolver estas ecuaciones
1: 3x+8=24
2. 9x-3=21
3: 1/2x+3/4=1/8
4: 2(x+1)-(x-1)=0
5: 2(x-1)=2x+3

Answer 1

1. 3X+8=24
3X= 24-8
3X=16
X= 16/3

2. 9X-3=21
9X=21+3
9X= 24
X= 24/9

3. 1/2X+3/4= 1/8
1/2X=1/8-3/4
1/2X= -20/32 = -5/8
X= -5/8 : 1/2
X= -10/8 = -5/4

4. 2(X+1)-(X-1)=0
2X+2-X+1=0
2X-X=-2-1
1X=1
X= 1/1
X= 1

5. 2(X-1) = 2X+3
2X-2= 2X+3
2X-2X=3+2
X=5
