Answer:
x=5,y=1 and z=-2
Step-by-step explanation:
We are given that system of equation
(I equation)
(II equation )
(III equation )
Equation II multiply by 3 then add with equation I
Then, we get
....(Equation IV)
Subtract equation II from equation III then we get
(equation V)
Adding equation IV and equation V then, we get

Substitute x=5 in equation V then, we get




Substitute x=5 and y=1 in equation then, we get




Hence, the solution for the given system of equation is given by
x=5,y=1 and z=-2
Square root of 1001=10.0033
square root of 1000=10
so 10.0033-10=0.0033
1/10=0.1
so, 1/10 is bigger than square root of 1001- square root of 1000
Answer:
t=5s-3
Step-by-step explanation:
Flip the equation:
5s+t=-3
then add 5s to both sides:
-5s+t+5s=-3+5s
then solve:
5s-3=t
You could put the ‘+6’ at the start of the equation so it would read as +6(x2+8x) and then expand the bracket as you normally would so you would get x2x6 which would get you 12x and then 6x8x which would get you 48x and then you could group both numbers together as they’re like terms and your final answer would be 60x
