Answer:

x = (z-y)/(a-b)

Step-by-step explanation:

Given ax-bx+y=z, we are asked to isolate x. To do so, first take common factor between the first and the second terms

ax-bx+y=z  

(a-b)*x+y = z

Then, isolate the x term by subtracting y at both sides

(a-b)*x+y-y = z-y

(a-b)*x = z-y

Finally, divide by (a-b) at both sides

(a-b)*x/(a-b) = (z-y)/(a-b)

x = (z-y)/(a-b)

Answer: z-y+bc/a

Step-by-step explanation:

ax-bc+y=z

ax-bc=z-y

ax=z-y+bc

x=z-y+bc/a

Theodore invests a total of $17,500 in two accounts paying 2% and 12% annual interest, respectively. How much was invested in ea
iVinArrow [24]

Answer:

11,500 at 2% and $6,000 at 12%.

Step-by-step explanation:

Let x represent amount invested at 2% and y represent amount invested at 12%.

We have been given that Theodore invests a total of $17,500 in two accounts. We can represent this information in an equation as:

x+y=17500...(1)

x=17500-y...(1)

We are also told that he invested $17,500 in two accounts paying 2% and 12% annual interest, respectively. After one year, the total interest was $950.00.

Interest earned at 2% in one year would be 0.02x.

Interest earned at 12% in one year would be 0.12y

0.02x+0.12y=950...(1)

Upon substituting equation (1) in equation (2), we will get:    

0.02(17500-y)+0.12y=950

350-0.02y+0.12y=950

350+0.10y=950

350-350+0.10y=950-350

0.10y=600

\frac{0.10y}{0.10}=\frac{600}{0.10}

y=6000

Therefore, Theodore invested $6,000 at 12%.

Upon substituting y=6000 in equation (1), we will get:

x=17500-6000

x=11500

Therefore, Theodore invested $11,500 at 2%.
