You would not subtract 2 from 6 because they are not like terms that you can combine - one of them contains a variable.
You would solve this equation like so:
6z - 2 = 0 The given equation
6z = 2 Add 2 to both sides
z = 1/3 Divide both sides by 6
Answer:
z = 1/3
Hope this helps.
Answer:
f^-1(x)=³√[(x+7)÷4]
Step-by-step explanation:
f(x)=4x^3-7
y=4x^3-7
interchange 'y' with 'x'
x=4y^3-7
make y the subject
4y^3=x+7
divide by 4 both sides
y^3=(x+7)÷4
multiply by the cube root both sides
³√(y^3)=³√[(x+7)÷4]
y=³√[(x+7)÷4]
f^-1(x)=³√[(x+7)÷4]
Answer:
x < 5
Step-by-step explanation:
–16x > –80
Divide each side by -16, remembering to flip the inequality
-16x/-16< -80/-16
x < 5
First subtract 3 from 51 which gives you 48, then divide 48 by 3 which gives you the answer of 16.
Answer:
<em><u>x=−2</u></em> if i could get brainliest that would be great
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(−x+2x+1)=x−1
(3)(−x)+(3)(2x)+(3)(1)=x+−1(Distribute)
−3x+6x+3=x+−1
(−3x+6x)+(3)=x−1(Combine Like Terms)
3x+3=x−1
3x+3=x−1
Step 2: Subtract x from both sides.
3x+3−x=x−1−x
2x+3=−1
Step 3: Subtract 3 from both sides.
2x+3−3=−1−3
2x=−4
Step 4: Divide both sides by 2.
2x/2=−4/2
x=−2
