DeShaun solves the following problem: “Martyn is 7 years older than Adele. If Martyn is 52 years old, how old is Adele?” DeShaun begins by writing the equation a+7=52 , using a as a variable to stand for Adele’s age. What is DeShaun’s next step
DeShaun's next step would be to isolate the variable 'a' by subtracting 7 from both sides of the equation. This would give him 'a = 52 - 7'.
He adds 7 to both sides of the equation.
He adds 7 to both sides of the equation.
He subtracts 7 from just the left side of the equation.
He subtracts 7 from just the left side of the equation.
He subtracts 7 from both sides of the equation.
He subtracts 7 from both sides of the equation.
He divides both sides of the equation by 7.
The correct next step for DeShaun would be to subtract 7 from both sides of the equation:
a + 7 - 7 = 52 - 7
After simplifying, he would get:
a = 45
so wicth one is it
Apologies for the confusion. The correct next step for DeShaun would be to subtract 7 from both sides of the equation:
a + 7 = 52
a + 7 - 7 = 52 - 7
a = 45
