3x=18 what is the answer
2 answers:
Answer: x = 6
Step-by-step explanation: To solve for <em>x</em> in this equation, we want to get <em>x</em> by itself on the left side of the equation.
Since <em>x</em> is being multiplied by 3, to get <em>x</em> by itself, we need to divide by 3 on the left side of the equation. Since we divide by 3 on the left side, we must also divide by 3 on the right side. On the left side, notice that the 3's cancel out so we are simply left with <em>x</em>. On the right side, we have 18 divided by 3 which is 6 so we have <em>x = 6</em>.
Finally, remember to check your answer by substituting a 6 back into the original equation. So we have 3(6) = 18 which is a true statement so our answer, <em>x = 6</em>, is correct. <em>Image if provided below</em>.
