The steps :

  • given
  • subtraction property of equality
  • subtract
  • division property of equality
  • divide
<h3>Further Explanation </h3>

One variable linear equation is an equation that has a variable and the exponent number is one. Can be stated in the form:

\large{\boxed{\bold{ax=b}}}

or

ax + b = c, where a, b, and c are constants, x is a variable

Whereas the two-variable linear equation is a linear equation that has 2 variables and the exponent is one

Can be stated in the form:

 \large{\boxed{\bold{ax+by=c}}}

ax + by = c

x, y = variable

There are 2 general steps to solving a linear equation of one variable:

  • 1. add or subtract both segments with the same number so that it is expected that in one segment there are only variable modifiers or constant numbers
  • 2. Change the equation into a simple form so that the coefficient of the variable is 1

This can be done by dividing or multiplying by equal numbers

An equation will remain equivalent if both segments are multiplied or divided by the same number

In the equation

2x + 5 = 19

The right steps to complete it according to the images included are:

  • 1. 2x + 5 = 9 ⇒ given
  • 2. both segments are subtracted by the number 5

 2x + 5 -5 = 9-5  ⇒subtraction property of equality

  • 3. 2x = 14  ⇒subtract
  • 4. both segments are divided by 2 so that the coefficient x = 1

{\displaystyle  {\frac {2x} {2}}=~\frac{14}{2}

⇒division property of equality

  • 5. x = 7 ⇒ divide

It is the steps to get to that certain step
some of the steps are out of order
I'm going to assign letters

the order is
A: 2x+5=19
B: 2x+5-5=19-5
C: 2x=14
D: 2x/2=14/2
E: x=7


A: given
B: we subtracted 5 from both sides so subtraction property of equality
C: subtract
D: divison property of equality (we divide both side by 2)
E: divide

Answer:

a. 2^4 or 16

b. 324

Step-by-step explanation:

a. I think you can take 4 and put it as the exponent using properties of logs. so it becomes ln 2^4

b. you use the same property and get

ln 6^2 + ln 3^2 and use the addition/multiplication property one to combine them and get

ln 6^2 * 3^2

or ln 36 * 9

or ln 324

hopefully that works

solniwko [45]

Answer:

Bola is 8 years old.

Step-by-step explanation:

Let Bola's age be x

Dada's age be y

Ayo's age be z

If the sum of ages of Bola, Dada and Ayo is 32 years, then;

x + y + z = 32

If they share a sum of money in ratio of their ages, then the ratio of their ages will be x : y : z

Also if Bola gets N400, Dada get-N400 and Ayo get N800, then the total amount of money shared will be expressed as:

T = 400 + 400 + 800

T = N1600

Next is to get the age of Bola

\frac{age \ of \ bola}{32}* Total \ amount \ shared = Bola's \ Share

Substitute the required variables and values into the formula;

\frac{x}{32}*1600= 400\\50x=400\\x=\frac{400}{50}\\x=8

This shows that Bola is 8 years old
