Answer:
x = 30
Step-by-step explanation:
First you would add the like terms, which are 2x and 4x, which gives you 6x. Now the equation would read 6x + 6 = 180
You need to get rid of the six, and since what you do to one side of the equation must be done to the other, you need to subtract 6 from both sides to cancel out the 6 on the left side of the equation. The equation is now 6x = 180. Now you need to divide both sides by 6, which gives you x = 30.
Answer:
£714.00
Step-by-step explanation:
The first step is to set up expresssions for the two shares:
Let x = the amount of one share. The other share is 1785 - x. <u>You don't have to worry about which is smaller--that part will work out automatically</u>!
The two shares are in the ratio of 2:3, so set up the proportion
Again, you don't have to worry--you could set up the proportion "upside down" and everything will work out in the end.
Solve the proportion for x by "cross multiplying" -- use the Means-Extremes Property of proportions.
So one share is £714£ and the other is £1785 - £714 = £1071.
The smaller share is £714.
