Answer:

a = 6   b=  7

Step-by-step explanation:

4 (b-1) = 3b + 3       substitue for a

4b - 4 = 3b + 3       subtract 4b from both sides

-4 = 3b + 3 - 4b       =        -4 = -b + 3        combine 3b and (-4b)

-7 = -b      divide by -1 for both sides

7 = b


4a = 3 × 7 + 3       substitute for b

4a = 24             combine like terms

a = 6       divide by 4 on both sides


a = 7 -1

a = 6

A student has a 2% salt water solution and a 7% salt water solution. To best imitate salt water at a local beach, he needs 1 lit
FromTheMoon [43]

Let

x-------> the amount of 2\% solution

y--------> the amount of 7\% solution

we know that

2\%=0.02\\7\%=0.07\\3.5\%=0.035

so

x+y=1

y=1-x -------> equation A

0.02x+0.07y=0.035 -------> equation B

substitute equation A in equation B

0.02x+0.07(1-x)=0.035

0.02x+0.07-0.07x=0.035

0.05x=0.035

x=0.7\ liters

find the value of y

y=1-x

y=1-0.7=0.3\ liters

therefore

The student need 0.7\ liters of 2\% solution and 0.3\ liters of 7\% solution

<u>the answer is</u>

A) The percent values were written incorrectly in the equation

B) The amount of 7% solution should be written as 1 – x, not x – 1.
