Answer:
x = 11.2
Step-by-step explanation:
-5x - 12y = -8
5x + 2y = 48
you can combine all like terms from both equations together:
0x-10y=40
simplified:
-10y=40
y=-4
now you plug in the value of y into either equation:
5x+2(-4)=48
simplify
5x-8=48
add 8
5x=56
divide by 5
x=56/5=11.2

Answer:
4.618
Step-by-step explanation:
Let's use x to represent the number so we can write an equation to solve it.
'twice the number' is represented by 2x so we have our equation:
2x-5^0.5=7
(5^0.5 is just square root 5 because I can't do a square root symbol.)
Now we need to isolate the x term so:
2x-5^0.5+5^0.5=7+5^0.5
2x=7+5^0.5
Square root 5 = 2.236 (3dp)
2x=7+2.236
2x=9.236
2x/2=9.236/2
x=4.618
Hope this helped!
