X=2
So you solve for x by simplifying bath sides of the equation, then all you do is isolate the variables
Answer:
If written in algebraic form it is, 10x - 4 = 11
Step-by-step explanation:
Four less ( minus 4 ) than the product of ten and a number ( 10 times x ) is eleven ( equal to 11 ).
Hopefully this helps!

Answer:
48
Step-by-step explanation:Its because they stated that f(1)= 8 so something times one = 8 which would of course be 8 so now u know that f=8 then u do 8(6) which is 48
Answer:
i got the same problem
Step-by-step explanation:
1] y - 3x = -8
[2] y + 9x = 4
-3x + y = -8 9x + y = 4
Solve equation [2] for the variable y
[2] y = -9x + 4
// Plug this in for variable y in equation [1]
[1] (-9x+4) - 3x = -8
[1] - 12x = -12
// Solve equation [1] for the variable x
[1] 12x = 12
[1] x = 1
// By now we know this much :
y = -9x+4
x = 1
// Use the x value to solve for y
y = -9(1)+4 = -5
{y,x} = {-5,1}
