Answer: 56 large cars and 86 small cars.

Step-by-step explanation:

Let's call:

$l$ : the number of large cars.

$s$ : the number of small cars.

Then, you can set up the following system of equations:

$\left \{ {{l+s=142} \atop {5.50l+4.0s=652.50}} \right.$

You can use the Elimination Method:

- Multiply the first equation by -4.0

- Add both equations.

- Solve for l.

$\left \{ {{-4.0l-4.0s=-568} \atop {5.50l+4.0s=652.50}} \right.\\--------\\1.5l=84.5$

$l$ ≈ $56$

Substitute $l=56$ into one of the original equations and solve for s:

$56+s=142\\s=142-56\\s=86$

What is the solution to the equation 1/2 x + 3 = 2/3 x + 1

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$\frac{1}{2} x + 3 = \frac{2}{3} x + 1 \\$

Subtract sides 3

$\frac{1}{2} x + 3 - 3 = \frac{2}{3} x + 1 - 3 \\$

$\frac{1}{2} x = \frac{2}{3} x - 2 \\$

Multiply sides by 6

$6 \times \frac{1}{2} x = 6 \times \frac{2}{3} x + 6 \times ( - 2) \\$

$3x = 4x - 12$

Subtract sides 4x

$- 4x + 3x = - 4x + 4x - 12$

$- x = - 12$

Negatives simplifies

$x = 12$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

CHECK :

$\frac{1}{2} (12) + 3 = \frac{2}{3} (12) + 1 \\$

$6 + 3 = 8 + 1$

$9 = 9$

Thus the solution is correct .
