What is the solution of 4+ sqrt 5x+66=x+10
viktelen [127]

Answer:

x=−48.541019

Step-by-step explanation:

4+√5x+66=x+10

Simplifies to:

2.236068x+70=x+10

Let's solve your equation step-by-step.

2.236068x+70=x+10

Step 1: Subtract x from both sides.

2.236068x+70−x=x+10−x

1.236068x+70=10

Step 2: Subtract 70 from both sides.

1.236068x+70−70=10−70

1.236068x=−60

Step 3: Divide both sides by 1.236068.

1.236068x

1.236068

=

−60

1.236068

x=−48.541019
