Impara online a risolvere i problemi di equazioni passo dopo passo. Solve the equation (2x+7)^3+31=4. Applicare la formula: x+a=b\to x=b-a, dove a=31, b=4, x+a=b=\left(2x+7\right)^3+31=4, x=\left(2x+7\right)^3 e x+a=\left(2x+7\right)^3+31. Applicare la formula: a+b=a+b, dove a=4, b=-31 e a+b=4-31. Applicare la formula: x^a=b\to \left(x^a\right)^{inverse\left(a\right)}=b^{inverse\left(a\right)}, dove a=3, b=-27, x^a=b=\left(2x+7\right)^3=-27, x=2x+7 e x^a=\left(2x+7\right)^3. Applicare la formula: x+a=b\to x=b-a, dove a=7, b=-3, x+a=b=2x+7=-3, x=2x e x+a=2x+7.
