Four times the sum of a number and -3 is 7 more than quadruple the number. What’s the equation?

Let the unknown number be x.

4(x + (-3)) = 7 + 4x

4x - 12 = 7 + 4x.

-12 ≠ 7

There is no equation cause this is cannot happen.

Help needed please im stuck

Answer:

a) b^3

b) x^3

Step-by-step explanation:

It can be helpful to think of the exponent as specifying the number of times the base is a factor in the product. Of course, common factors in the numerator and denominator cancel.

$\dfrac{b^7}{b^4}=\dfrac{b\cdot b\cdot b\cdot b\cdot b\cdot b\cdot b}{b\cdot b\cdot b\cdot b}=b\cdot b\cdot b=b^{7-4}=\boxed{b^3}$

$\dfrac{x\cdot x^5}{x^2\cdot x}=\dfrac{x\cdot x\cdot x\cdot x\cdot x\cdot x}{x\cdot x\cdot x}=x\cdot x\cdot x=x^{6-3}=\boxed{x^3}$
