Answer:
Equation:
2(a+9) = a/2
Solve:
The umber is:
-12
Step-by-step explanation:
Equation:
2(a+9) = a/2
Solve:
2*a + 2*9 = a/2
2a + 18 = a/2
2a - a/2 = -18
4a/2 - a/2 = -18
3a/2 = -18
a = -18*2/3
a = -12
Check:
2(-12+9) = -12/2
2(-3) = -12/2 = -6
Answer:
See below
Step-by-step explanation:
"Like terms" are terms with the same variable or exponents.
You can add or subtract these just like you would with regular numbers.
Examples:
2x + 4x = 6x
5xy + 7xy = 12xy
6 + 5 = 11

Answer:
x = - 1/18
Step-by-step explanation:
Move all terms not containing x to the right side of the equation
Divide each term by 18 and simplify
The result can be shown in multiple forms
x = -1/18
Decimal form= -0.05
751.2 divided by 25 is 30.048.
