Answer:
-23
Step-by-step explanation: You have to combine like terms first:
-3.8x -5.9x =223.1
-9.7x = 223.1
Then divide om each side of the equation by -9.7.
-9.7x/-9.7 = 223.1/-9.7
x =- 23
Answer:
x=-23
Step-by-step explanation:
-<u>3.8x</u>-<u>5.9x</u>=223.1
Collect like terms by calculating the sum or difference of their coefficients
(-3.8-5.9)x
calculate the difference
-<u>9.7x</u>=223.1
Divide both sides of the equation by -9.7
-9.7x÷(<u>-9.7</u>)=223.1÷(<u>-9.7</u>)
Any expression divided by itself equals 1
x=223.1÷(-9.7)
x=-23

She originally had $400 in her bank account.
The 50w represents the amount she will put away each week.
Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90
