9 squares because if there are 18 triangles in it then you divide 18 by 2 and get 9

What is the result of adding these two equations? 6 x + 2 y = − 2 3 x − 2 y = − 5 6x+2y 3x−2y ​ =−2 =−5 ​
stellarik [79]

Answer:

The result gives the equation: 9x = -7

solution:  (-7/9, 4/3)

Step-by-step explanation:

6 x + 2y = − 2

and

3 x − 2y = − 5

add together

6x + 3x + 2y - 2y = -2 + -5

9x + 0 = -7

9x = -7

then x = -7/9

and y = -3x - 1:

y = -3*(-7/9) - 1

y = 7/3 - 1 =  4/3

solution:  (-7/9, 4/3)

-----------------------------------------

6x+2y= -2   and 3x−2y ​ =−5 ​

6x + 3x  + 2y - 2y = -2 + -5

Answer:

  • Architect - $83000
  • Lawyer - $128000

Step-by-step explanation:

  • Salary of a lawyer = l
  • Salary of an architect = a

<u>According to the question we have:</u>

  • l = 2a - 38000
  • l + a = 211000

<u>Substitute l into the second equation and solve for a:</u>

  • 2a - 38000 + a = 211000
  • 3a = 211000 + 38000
  • 3a = 249000
  • a = 249000/3
  • a = 83000

<u>Find the value of l:</u>

  • l = 211000 - 83000
  • l = 128000
