Question

Help solve pls ^-^

1.23 = x – 9.5
2.12 = k – 4.3
3.r – 20 = 32
4.d – 10 = 25
5.n – (-8) = -18
6.c – (-2.6) = -14.9

Answer 1

Explanation:

`1.\ x-9.5=1.23\qquad\text{add 9.5 to both sides}\\\\\boxed{x=10.73}\\\\2.\ k-4.3=12\qquad\text{add 4.3 to both sides}\\\\\boxed{k=16.3}\\\\3.\ r-20=32\qquad\text{add 20 to both sides}\\\\\boxed{r=52}\\\\4.\ d-10=25\qquad\text{add 10 to both sides}\\\\\boxed{d=35}\\\\5.\ n-(-8)=-18\\\\n+8=-18\qquad\text{subtract 8 from both sides}\\\\\boxed{n=26}\\\\6.\ c-(-2.6)=-14.9\\\\c+2.6=-14.9\qquad\text{subtract 2.6 from both sides}\\\\\boxed{c=-17.5}`
