Answer:
x=−2y+4
Step-by-step explanation:
1. flip equation
−1/
2
x+1=y−1
2. add -1 to both sides
−1
/2
x+1+−1=y−1+−1
−1
/2
x=y−2
3. divide both sides by (-1)/2

Answer:
A:
2(x + 2) + 2(2x - 5) =
2x + 4 + 4x - 10 =
6x - 6
perimeter = 6x - 6
B:
(x+2)(2x - 5) expand the brackets:
2x² - 5x + 4x - 10
area = 2x² - x - 10
C:
area = 6x - 6 = (6 x 5) - 6 = 30 - 6 = 24
perimeter = 2x² - x - 10 = (2 x 5²) - 5 - 10 = (2 x 25) - 5 - 10 = 50 - 5 - 10 = 35

Simple, writing an equation,
(x-5)*4+7=35
multiply the 4 in
4x-20+7=35
4x-13=35
add 13 to the other side
4x-13=35
+13 +13
4x=48
x=12.
The number is 12. But to check it, substitute the 12 into the equation.
(12-5)*4+7=35
(7)*4+7=35
28+7=35
35=35.
Thus, your answer is , the number is 12.
