Solve simultaneous equations 5x+2y=13 2x+6y=26

x = 1 and y = 4

Step-by-step explanation:

5x+2y+2x+6y = 39

7x+8y = 39

Trial and error method:

the answer that satisfies the equation are: x = 1 and y = 4

Hope this helps.

Good Luck

(1, 4 )

Step-by-step explanation:

Given the 2 equations

5x + 2y = 13 → (1)

2x + 6y = 26 → (2)

Multiplying (1) by - 3 and adding to (2) will eliminate the term in y

- 15x - 6y = - 39 → (3)

Add (2) and (3) term by term to eliminate y

- 13x = - 13 ( divide both sides by - 13 )

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (1)

5(1) + 2y = 13

5 + 2y = 13 ( subtract 5 from both sides )

2y = 8 ( divide both sides by 2 )

y = 4

Solution is (1, 4 )

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
