HOW DO U DO THIS!?

2x+3=13

Answer 1

x=5

Explanation:

To solve for x you must do inverse operations. Inverse operations is when you do the opposite to remove a part of the equation which you want to get red of addition and subtraction before multiplication and division.

2x+3=13

First we need to get rid of the "+3" by subtracting 3 (from both sides of the equation so each side remains equal). We will get ridd of the +3 on the left and subtract 3 from 13 on the right (13-3=10).

2x=10

Now we divide by 2 on both sides the same way we did with subtracting the 3 (10÷2=5).

x=5

Answer 2

x = 5

Explanation:

Solve for x:

2 x + 3 = 13

Hint: | Isolate terms with x to the left hand side.

Subtract 3 from both sides:

2 x + (3 - 3) = 13 - 3

Hint: | Look for the difference of two identical terms.

3 - 3 = 0:

2 x = 13 - 3

Hint: | Evaluate 13 - 3.

13 - 3 = 10:

2 x = 10

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = 10 by 2:

(2 x)/2 = 10/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

x = 10/2

Hint: | Reduce 10/2 to lowest terms. Start by finding the GCD of 10 and 2.

The gcd of 10 and 2 is 2, so 10/2 = (2×5)/(2×1) = 2/2×5 = 5:
