2x+3x+x+9 = ??
5x+x+9 = ??
6x+9= ??
6x = -9 ---- subtract 9 on both sides
x = - 3/2 ----- didvide by 6 on both sides, simplify

Answer:
x = 3/10
Step-by-step explanation:
−1/2 − (−4/5) = x
First, switch sides.
x = −1/2 − (−4/5)
You are subtracting a negative number. Subtracting a negative number means add a positive number.
x = -1/2 + 4/5
Now you are adding two fractions, so you need a common denominator. The LCD of 2 and 5 is 10.
x = -5/10 + 8/10
x = 3/10
Xy = 6
x = 2
2y = 6
y = 6÷2
y = 3
x + y = (2) + (3) = 5
3^7 when you are multiplying numbers with the same base add the exponents.
