Answer 2

A.

1. 5x + 12=2x-3

• 5x-2x= -12-3
• 3x/3= -15/3
• x = -5

2. 3x+6= -2x+1

• 3x+2x= -6+1
• 5x/5= -5/5
• x= -1

3. (x/2-4x=7)x2

• 2(x/2) - 2(4x)=7x2
• x-8x=14
• -7x/-7=14/-7
• x= -2

4. 1.4x - 0.4x=6.2+3.8

• 1x/1=10/1
• x=10

5. 5x-10+2x=7x+28-38

• 5x+7x-10=7x+28-38
• 12x-10=7x+28-38
• 12x-7x=28+10-38
• 5x=38-38
• 5x/5=0/5
• x=0

B.

1. 2x/2 ≤ 4/2

• x=2

2. 2x+3 > -3

2x+3< 15

• x= -3
• x= 6
• X=(-3,6)

3. 5x-4 >6

• 5x>6+4
• 5x/5 >10/5
• x >2

4. (2x./3+1/2>x-5)x6

• 6(2x/3)+6(1/2) > 6(x-5)
• 4x+3 > 6x-30
• 4x-6x>-30-3
• -2x/-2 > -33/-2
• x< 33/2

5. 0.8+0.6x ≥4.2

• 0.6x≥4.2-0.8
• 0.6x/0.6 ≥3.4/0.6
• x= 5.666666667
