Hey!
QUESTION #1
The first step to solving this equation would be to switch the sides of the equations. Doing this will make the equation much more easier to read and solve.
Original Equation :
5.4 = a - ( -1.8 )
New Equation {Changed by Switching Sides} :
a - ( -1.8 ) = 5.4
Next we'll have to simplify the equation. This will get rid of the any negatives in the equation.
Old Equation :
a - ( 1.8 ) = 5.4
New Equation {Changed by Applying Rule} :
a + 1.8 = 5.4
Now we'll add subtract 1.8 from both sides of the equation to get 1.8 on its own.
Old Equation :
a + 1.8 = 5.4
New Equation {Added Subtract 1.8} :
a + 1.8 - 1.8 = 5.4 - 1.8
Solution {New Equation Solved} :
a = 3.6
So, this means that in the equation 5.4 = a - ( -1.8 ), a = 3.6.
QUESTION #2
The first step to solving this equation would be to simplify it. This will get rid of the two negatives in the equation.
Original Equation :
g + ( -5 ) = 27
New Equation {Changed by Simplification} :
g - 5 = 27
Now we'll add five to both sides of the equation to get g on its own.
Old Equation :
g - 5 = 27
New Equation {Added Add 5 to Both Sides} :
g - 5 + 5 = 27 + 5
Solution {New Equation Solved} :
g = 32
So, this means that in the equation g + ( -5 ) = 27, g = 32.
QUESTION #3
The first and basically the only step to solving this equation would be to subtract 47 from both sides of the equation. This would give us x on its own.
Original Equation :
x + 47 = -23
New Equation {Added Subtract 47 to Both Sides} :
x + 47 - 47 = -23 - 47
Solution {New Equation Solved} :
x = -70
So, this means that in the equation x + 47 = -23, x = -70.
Hope this helps!
