Substitution Method:

3x - 10 = 2x - 5

3x = 2x + 5

x = 5

Now solving for y:

y = 3x - 10

y = 3(5) - 10

y = 15 - 10

y = 5

(x, y) = (5, 5)

Check answer:

5 = 3(5) - 10
5 = 15 - 10
5 = 5

5 = 2(5) - 5
5 = 10 - 5
5 = 5

Since all of the equalities are true, (5, 5) is a true solution

How to answer this question, please I need steps​

Answer:

B

Step-by-step explanation:

We require 2 equations in 2 variables

let x be the number of salads sold and y the number of drinks sold, then the 2 equations are

x + y = 209 → (1)

6.5x + 2y = 836.5 → (2)

Multiplying (1) by - 2 and adding to (2) will eliminate y

- 2x - 2y = - 418 → (3)

Add (2) and (3) term by term

(6.5x - 2x) + (2y - 2y) = (836.5 - 418) ← simplify

4.5x = 418.5 ( divide both sides by 4.5 )

x = 93

The number of salads sold was 93

Answer:

  18

Step-by-step explanation:

Solve the first for a, then substitute into the second.

  a = 27/(5b^2)

Then ...

  (27/(5b^2))^2·b = 135

  27^2/(5^2·135) = b^3 = 27/125

  b = ∛(27/125) = 3/5

  a = 27/(5(3/5)^2) = 15

__

The expression of interest is ...

  a +5b = 15 + 5(3/5) = 15 +3

  a +5b = 18
