Answer:
a = -10
Step-by-step explanation:
33 - 4a = 73
To get <em>a</em> by itself, you must move 33 to the other side. To this, you must subtract it from both sides, canceling it out on the left side.
You will be left with: -4a = 73-33
Subtract 73 and 33, which will get you 40.
Now the equation is -4a = 40
To get <em>a </em>by itself, divide -4 into both sides. Doing this will isolate <em>a</em>.
The equation you will have after that is a = 40/-4.
Divide 40 by -4, which will get you -10.
Therefore, a = -10.
Well lets do this
3 + 16 ÷ 4
we divide first
3 + 4

Answer:
28
Step-by-step explanation:
Mikhail's age:x
Gabrielle's age:2x
x+2x=84
3x=84
x=84÷3
x=28
Step-by-step explanation:
(2x-12)+(1/2xy-10)
- (2×8-12)+(1/2×8×2-10)
- (16-12)+(8-10)
- 4+(-2)
- 4-2
- 2
