Answer: Here is the explanation. also it it +3y not -3y

Step-by-step explanation:

x+y+4+2y+1=x+3y+5 because

Answer:

The value of x is 7 and y is 14.

Step-by-step explanation:

The steps are :

$- 3x + y = - 7 - - - (1)$

$y = x + 7 - - - (2)$

$(2)→(1)$

$- 3x + (x + 7) = - 7 \\ - 3x + x + 7 = - 7 \\ - 2x = - 14 \\ x = 7$

$substitute \: x = 7 \: \: into \: \: (2)$

$y = 7 + 7 \\ y = 14$

Helga [31]

Answer:

6 cm by 6 cm

Step-by-step explanation:

We know that the formula for area of a square is A = s² where A = area and s is the length of one side. We know that A = 36 so:

36 = s²

√36 = s

s = ±6

Note that s = -6 is an extraneous solution because you can't have a side length of -6, therefore the answer is s = 6 so the dimensions of the square are 6 cm by 6 cm.
