We are given the following equation and want to find which value of x will make it true:
Subtract 3 from both sides
Divide both sides by -6
Thus, the value that will make 3-6x=21 is x=-3. Let me know if you need any clarifications, thanks!

Given equation : .
Strategy 1: We can cross mutiply both sides remove fraction form.
On cross multiplication, we get
x * 7 = 3 * 42
7x = 126.
Dividing both sides by 7, we get
<h3>x = 18.</h3>Strategy 2: We can find least common denominator(lcd) of both sides and multiplying both sides by that lcd to get rid denominators from both sides.
LCD of 42 and 7 is 42.
Therefore, multiplying both sides by 42, we get
x = 6 * 3
<h3>x = 18.</h3>
