Step-by-step explanation:

make the coefficients same

then if sign are same subtract the one you wanna cancel it then here it goes

lam gonna start making coefficient of x sam like this:

4.X+7y= -37

1.4X-3y=7

then i will subtract all x or cancel to each other then

4X+28y= -148

-

4X-3y=7

and then -×-=+

add all y

31y=141

y= 4.55 then we take one of the equation then substitute y to 4.55 so i chose first equation

X+7(4.55)=-37

X+31.85=-37

so take 31.85 to the side it will become -31.85

then X=-37-31.85

X=68.85

i hope that it will help you

Find the value of x in kite EFGH<br>​
kolbaska11 [484]

Answer:

x = 105

Step-by-step explanation:

the sum of all interior angles of any four-sided figure has 360 degrees

∡F and ∡H are equal

add all four expressions and set them equal to 360

x + (x + 5) +( x + 5) + (140 - x) = 360

combine like terms

2x + 150 = 360

2x = 210

x = 105
