Okay so, you would just have to simply do one step for this literal equation.
x-b=a
+b +b
x=a+b
You would just have to add b to both sides to cancel out the -b on the left side because you have to isolate x to solve for x. So you add b to both sides, and then the -b gets cancelled out and the right side becomes a+b.
So x = a+b
Hope this helped!
Answer:
1) B/ 0.4n = 12; n = 30
2) B/ 125 – x = 58
3) B/ $1.75
Step-by-step explanation:
1) 0.4n = 12
n = 12 ÷ 0.4
n = 30
2) 125 – x = 58
– x = 58 – 125
– x = – 67 ( – & – will get cancelled)
x = 67
a) 125 + x = 58
x = 58 – 125
x = – 67 (pages won't be in negative)
c) 125 ÷ 58 = x
2.15 = x (wrong)
d) 58 – x = 125
– x = 125 – 58
– x = 67
x = 67 ÷ –1
x = – 67 ( pages won't be in negative)
3) 12x = 21
x = 21 ÷ 12
x = 1.75
All sides are equal in a square



One side of the square measures 7+6 = 13
Hence, side DC is 13 units
