How is elementary? just wondering haha seems hard for a kid
The statement is true. The number is seven. I can find this through the commutative property of addition or plugging in the number and reversing the equation.
Key: a is 7, b is square root of five, c is solution, ? is what we're finding
Commutative: a + b = b + a
Plugging and Reversing: a + ? = c, c - a = b
Step by step: change 3 into a fraction- 3/1 • 3/4 multiply 3/4 • 3/1 =9/4 = 2 3/4
You subtract 3 with eleven and you're left with -2x>8 and then I think you divide them but I'm not 100% sure
