2x + 3y = 26 3x + 5y = 40 find x and y I will give brainliest

Yuki888 [10]

Answer:

x = 10 and y = 2

Step-by-step explanation:

multiply first equation by 5 and 2nd equation by 3 then subtract equation 1 and 2, we get,

10x+15y= 130

9x+15y=120

( -) (-) (-)

x= 10

substituting the value of x in equation 1 we get

2x + 3y = 26

2*10 + 3y = 26

3y = 26-20

y =6/3

y= 2.i hope this helps

Answer:

Question 10.

Length of the side of the square = $\sqrt{441} = 21$

By Pythagoras' Theorem,

Hypotenuse = $\sqrt{21^{2} + 20^{2} }$ (H > 0)

= 29 m

Ans: 29 m

Question 11.

By Pythagoras' Theorem,

Length of longer side of 42 km = 42- $\sqrt{18^{2} - 15^{2} }$ (L > 0)

= 32.050 km (5 s.f.)

By Pythagoras' Theorem,

Length of the unknown side = $\sqrt{32.050^{2} + 15^{2} }$ (L > 0)

= 35.4 km (3 s.f.)

Ans: 35 km
