Answer:
9 + b is an expression
Step-by-step explanation:
Expressions don't have the = sign in them but equations do.
Since it's a six dice then it's out of x/6
How much is 4 to 6 ?
~3 (counting 4) 4.5.6...
So it's 3/6 = 1/2
X = 15
X + 90 = 7x
X = 7x - 90
X - 7x = -90
-6x = 90
Divide both sides by -6
X = 15
Answer:
-2x
Step-by-step explanation:
The expression itself is -2x. We subtract the coefficients 7 and 9 to get -2.
