Solve 27=y³ where y is a real number

27 = 3³

3 · 3 · 3 = 27

do the opposite of the equation

so y = 3 to the third power.

step-by-step explanation: 4 cause 2+2=4

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
