Answer:

Explanation:

√2a-3-10=-7

We add 10 to both sides:

√2a - 3 = 3

Now we add 3 to both sides to isolate the radical term:

√2a = 6

Then, square both sides

(√2a)^2 = 6^2

2a = 36

Divide both sides by 2

a = 18

Therefore, the solution is a = 18.

Answer:

the solution to the equation √2a-3-10=-7 is a = 18.

Step-by-step explanation:Starting with the given equation:

√2a - 3 - 10 = -7

First, let's simplify the left-hand side by combining like terms:

√2a - 13 = -7

Next, we can isolate the variable term (√2a) by adding 13 to both sides:

√2a = 6

To solve for a, we need to square both sides of the equation:

(√2a)^2 = 6^2

2a = 36

Finally, we can solve for a by dividing both sides by 2:

a = 18

Therefore, the solution to the equation √2a-3-10=-7 is a = 18.
