Answer: x= -10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4.5(8−x)+36=102−2.5(3x+24)
(4.5)(8)+(4.5)(−x)+36=102+(−2.5)(3x)+(−2.5)(24)(Distribute)
36+−4.5x+36=102+−7.5x+−60
(−4.5x)+(36+36)=(−7.5x)+(102+−60)(Combine Like Terms)
−4.5x+72=−7.5x+42
−4.5x+72=−7.5x+42
Step 2: Add 7.5x to both sides.
−4.5x+72+7.5x=−7.5x+42+7.5x
3x+72=42
Step 3: Subtract 72 from both sides.
3x+72−72=42−72
3x=−30

Answer:
x=-9,y=-4
Step-by-step explanation:
2x-3y=-6...(1)
-2x-2y=26...(2)
To solve we will have to eliminate one of the given variables, the variable to be eliminated is x
And it can be done by adding up (1) and (2)
It gives
-5y=20
Divide both sides by-5
y=-4
Then substitute the value of y into (1)
2x-3(-4)=-6
2x+12=-6
Substrate 12 from both sides
2x=-18
Divide both sides by 2
x=-9
Therefore x gives -9 and y gives-4
Hey there! :)
Answer:
n = 12.
Step-by-step explanation:
Given:
5/6n = 10
Solve by isolating the variable. Divide both sides by 5/6. (Multiply by the reciprocal)
5/6n · 6/5 = 10 · 6/5
n = 10 · 6/5
n = 12.
