Answer:
The number is -1
Step-by-step explanation:
The equation for the first part is (2n+7)2. This is because "twice a number" is 2n and "7 is added" will make it 2n+7. The "sum is multiplied by two" Is multiplying everything by two. This will make it (2n+7)
The second part is -8n+2. Since a number is multiplied by negative eight it will be -8n. Then it is added by two.
Both equation equal each other the overall equation will be (2n+7)2=-8n+2
You will distribute. making it 4n+14=-8n+2
Add 8n to both sides making it 12n+14=2
subtract 14 from both sides making it 12n=-12
Divide both sides by 12 . making it number=-1
Step-by-step explanation:
the gradient of the line = 2 units/ 3 units = 2/3
Answer:
x = 6
Step-by-step explanation:
1/2(18-5x)=1/3(6-4x)
9 - 5/2x = 2 - 4/3x
7 = 7/6x
x = 6
X intercepts are 2 and -1/2
