Answer:
x = 5
Step-by-step 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:
Answer: x = 5
Answer:
x=5
Step-by-step 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
