Answer:
x = ±1
Step-by-step explanation:
=> 7x² = 13-6
=> 7x² = 7
<em>Dividing both sides by 7</em>
=> x² = 1
<em>Taking sqrt on both sides</em>
=> x = ±1
You can factor a 12 out from both. 12 goes into 12m 12 times and 12 goes into 60 5 times. So you would pull it out front:
12(m+5)
That's as far as you can take it. Do you have to set it equal to 0, or some other number??
Answer: x < 2
Step-by-step explanation:
Let's solve your inequality step-by-step.
6.2x+1<21−3.8x
Step 1: Simplify both sides of the inequality.
6.2x+1<−3.8x+21
Step 2: Add 3.8x to both sides.
6.2x+1+3.8x<−3.8x+21+3.8x
10x+1<21
Step 3: Subtract 1 from both sides.
10x+1−1<21−1
10x<20
Step 4: Divide both sides by 10.
10x/10 <20x/10
x < 2
