Answer:
5
Step-by-step explanation:
Given the equation 2x + 3(x + 4) = 37, to find x we will make x the subject of the formula. To do that, we need to first open the bracket of the equation to have;
2x+3x+12=37
5x+12 = 37
Taking +12 to the other side of the equation will change the sign to negative i.e -12 to give;
5x = 37-12
5x = 25
Dividing both sides the coefficient of x which is 5, we will have;
5x/5 = 25/5
x = 5
Since 5 is an element of the given set, 5 is therefore the element of the set that makes the equation true.
