- 10 + √(x + 8) = - 4

Add 10 to both sides to get:
√(x + 8) = 6

Square both sides to get our binomial out of the square root:
x + 8 = 6²
x + 8 = 36

Subtract 8 to both sides to get:
x = 28

Answer:

[tex]x=28[/tex]

Step-by-step explanation:

[tex]-10+\sqrt{x+8}=-4[/tex]

⭆ Add 10 to both sides:-

[tex]-10+\sqrt{x+8}+10=-4+10[/tex]

[tex]\sqrt{x+8}=6[/tex]

⭆ Square both sides:-

[tex]x+8=36[/tex]

⭆ Subtract 8 from both sides:-

[tex]x+8-8=36-8[/tex]

[tex]x=28[/tex]
