56+34=n+30? Do you add 56+34 =90-30=60 n=60?
2 answers:
56 + 34 = n + 30
90 = n + 30 <em>added like terms on the left side (56 + 34)</em>
<u> -30 </u> <u> -30 </u> <em>subtracted 30 from both sides to isolate n</em>
60 = n
You're on the right track. Start by combining like terms on the left side of the equation by adding 56 and 34.
90 = n + 30, now subtract 30 from both sides of the equation to isolate the variable n.
60 = n is the answer.
