4x-5y=39 y=6x-13how would you solve it and what system of equation is it

1 answer:

6 0

Hi there,

4x - 5y = 39
y = 6x - 13

4x - 5(6x - 13) = 39
4x - 30x + 65 = 39
-26x = 39-65
-26x = -26
x= -26/-26
x= 1

So we deduce y now :

y = 6 *1 - 13
y= 6 - 13 = -7

Hope this helps !

3² +4² = 5²,

AlekseyPX

Answer:

They are all true

Step-by-step explanation:

1. 3² +4² = 5²

3x3 + 4x4 = 5x5

9 + 16 = 25

25 = 25

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

2. 6² + 8² = 10²

36 + 64 = 100

100 = 100

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

3. 9² + 12² = 15²

81 + 144 = 225

225 = 225

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

4. 5² +12² =13²

25 + 144 = 169

169 =169
