Answer:
The correct answer is C
Step-by-step explanation:
To find the answer, solve the second equation for y.
y + 5 = -6x
y = -6x - 5
Now use that value for y in the first equation.
-4x + y = -2
-4x + (-6x - 5) = -2
-10x - 5 = -2
-10x = 3
x = -3/10
Now we can find y by putting the x term into the equation.
y + 5 = -6x
y + 5 = -6(-3/10)
y + 5 = 9/5
y = -16/5

Answer:
x=4
Step-by-step explanation:
4x-3=x+9
4x-x-3=9
4x-x=9+3
3x=9+3
3x=12
3/3
12/3=4
x=4
So it our equation would be t(5)=5^2+2(5) 25+10=35 :)
