Add 31 to both sides which will give you
9h = 130
Answer:
7x+21 = 7x + 21
Step-by-step explanation:
7(x+3)=6-(-7x - 15)
L.H.S
=7(x+3)
=7x+21 (multiply 7 by (x+3))
R.H.S:
=6-(-7x - 15)
= 6+7x+15 (multiply the -ive sign in the bracket)
= 7x + 21 ( adding 15 and 6)
now compare the two sides
7x+21 = 7x + 21 hence we prove that L.H.S= R.H.S
Answer:
<h2>7a +2.........................</h2>
Any answer is correct because when you plug in any number you'll get the same thing on both sides
3x-2=3x-2 (any value can be plugged in for x)
