Solve: sqrt(x + 3) = 7​

Sagot :

Ezekielsantos49idn

x=46

Step-by-step explanation:

(√x+3)2 = (7)2

x+3 = 49

x -46 = 0

Add 46 to both sides

x = 46

A possible solution is :

x = 46

Original equation

√x+3 = 7

Plug in 46 for x

√(46)+3 = 7

Simplify

√49 = 7

Solution checks !!

Solution is:

x = 46
