Answer:
Division property
Step-by-step explanation:
The property which states that we can divide both side of the equation by the same non-zero number is called the division property of equality.
The goal of dividing an equation is to isolate the unknown variable on one side.
For example, let the equation be:
2×x=10
Since the unknown variable x is being multiplied by the number 2, to isolate the variable an inverse operation needs to be applied - division:
2×x÷2=10÷2
Careful! Never forget to write the same operation on both sides of the equation! When doing so, the solution of the equation stays the same, i.e. we get an equivalent equation.
Step-by-step explanation:
5-2(x+1)=13 what is x
Answer:
x=-5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5−2(x+1)=13
5+(−2)(x)+(−2)(1)=13 (Distribute)
5+−2x+−2=13
(−2x)+(5+−2)=13 (Combine Like Terms)
−2x+3=13
−2x+3=13
Step 2: Subtract 3 from both sides.
−2x+3−3=13−3
−2x=10
Step 3: Divide both sides by -2.
−2x −2 = 10
−2 x=−5
Answer:
x=-5
[tex]\mapsto:\bold{5-2(x+1)=13 }[/tex]
[tex]\mapsto:\bold{-2(x+1)=13-5 }[/tex]
[tex]\mapsto:\bold{(-2\times x)+(-2\times 1)=8 }[/tex]
[tex]\mapsto:\bold{-2x+(-2)=8 }[/tex]
[tex]\mapsto:\bold{-2x-2=8 }[/tex]
[tex]\mapsto:\bold{-2x=8+2 }[/tex]
[tex]\mapsto:\bold{-2x=10 }[/tex]
[tex]\mapsto:\bold{ x=\dfrac{10}{-2} }[/tex]
[tex]\dashrightarrow:\bold{ x=-5 }[/tex]

Answer:
60 1/5
Step-by-step explanation:
(2 2/5 × 3 1/5) × 2 = 6 2/25
6 2/25 × 2 = 12 2/25
12 2/25 ÷ 1/5
302/25 × 5/1 = 1505/25
1505/25 = 60 5/25 = 60 1/5
