Answer:
B
Step-by-step explanation:
Answer:
27, you need to simplify both sides of the equation to get x on one side.
Step-by-step explanation:
<span>f(x) =6x +4 replace x with 10 and solve
f(x)= 6(10) + 4
f(x) = 64</span>
Answer:
x = -1
Step-by-step explanation:
2x - 7 = 9x
Subtract 2x from both sides: -7 = 7x
Divide both sides by 7: -1 = x
Now plug in 7 for every value of x in the original equation to make sure you are correct:
2(-1) - 7 = 9(-1)
-2 - 7 = -9
-9 = -9
I hope this helps!
