Answer:
Step-by-step explanation:
x + y = 4 ---------------(i)
x = 4-y
7x + 9y = 42 -----------(ii)
Plug in x = 4-y in equ (ii)
7*(4 - y) + 9y = 42
28 - 7y +9y = 42
28 + 2y = 42
2y = 42 - 28
2y = 14
y = 14/2
y = 7
x = 4 - y
x = 4 - 7
x = -3
64 inches is greater than 5 feet.

In expression x-2 coefficient of x is equal to one.
Let a be "a" x's coefficient.
If we put "a" to Your equation, it should be looks like:
ax-2
We know that there is only one x, so expression ax have to be equal x
Now we get
From this equation we know that coefficient x "a" is equal to 1.
Answer: 26
Step-by-step explanation:
Let the tens digit=x
and units digit=y
Hence sum x+y=8…………(i)
Number =10x+y
Number formed by reversing the digits =10y+x
(10y+x)=(10x+y)+36 i . e. 9y-9x=36
Or y=x+4…………..(ii)
Adding (i) and (ii) gives 2y=12
Hence y=6
hence from (i)
x=8-y
8–6 = 2
hence Number =26
