Answer:

b = 9

Step-by-step explanation:

Step 1: Add <em>b</em> on both sides (Addition Equality)

5/3b + 5 = 20

Step 2: Subtract 5 on both sides (Subtraction Equality)

5/3b = 15

Step 3: Divide both sides by 5/3 (Division Equality)

b = 9

Solve for x: 7-3x=-2/5x-69/5

san4es73 [151]

Answer:

x = 8

Step-by-step explanation:

Step 1: Simplify both sides.

7 - 3x = -2/5x - 69/5

7 + - 3x = -2/5x + -69/5

-3x + 7 = -2/5x + -69/5

Step 2: Add 2/5x to both sides.

-3x + 7 + 2/5x = -2/5x + -69/5 + 2/5x

-13/5x + 7 = -69/5

Step 3: Subtract 7 from both sides.

-13/5x + 7 - 7 = -69/5 - 7

-13/5x = -104/5

Step 4: Multiply both sides by 5/(-13)

(5/-13) * (-13/5x) = (5/-13) * (-104/5)

x=8

4. In your own words, describe how you can check to see if an ordered pair is a solution to a system of equations,

Alecsey [184]

Answer: To figure out if an ordered pair is a solution to an equation, you could perform a test or experiment . Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the value you get is the same as the value in the ordered pair, then that ordered pair is indeed a solution to the equation.
