Answer:
a= 13+3b
Step-by-step explanation:
Simplifying
a + -7 = 3(b + 2)
Reorder the terms:
-7 + a = 3(b + 2)
Reorder the terms:
-7 + a = 3(2 + b)
-7 + a = (2 * 3 + b * 3)
-7 + a = (6 + 3b)
Solving
-7 + a = 6 + 3b
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + a = 6 + 7 + 3b
Combine like terms: -7 + 7 = 0
0 + a = 6 + 7 + 3b
a = 6 + 7 + 3b
Combine like terms: 6 + 7 = 13
a = 13 + 3b
Simplifying
a = 13 + 3b
First lets make these numbers more simple...
9.1 x 10^2 = 910
918% = 918 (reason being percents are out of 100, so 100 = 100%, therefore 918% = 918) (this was wrong, its actually 918 / 100 = 9.18 by conversion of percent to decimal)
1830 / 2 = 915
920.0 = 920
Your arrangement: 920 , 918 , 915 , 910
Another way is: 920.0, 918% , 1830 / 2, 9.1x102
(answer is actually 920.0, 1830 / 2, 9.1 x 10^2, 918%)
