Question

(I will give brainliest) Please HELP me!!

Answer 1

Answer:

$1.3x - 5 = 25 \\ 3x = 25 + 5 \\ 3x = 30 \\ x = \frac{30}{3} = 10 \\ \\ - 4x +6 = 26 \\ - 4x = 26 - 6 \\ - 4x = 20 \\ x = - \frac{20}{4} = - 5 \\ \\ 7x - 8 = 50 \\ 7x = 50 + 8 \\ 7x = 58 \\ x = \frac{58}{7} = 8$

Answer 2

Answer:

1) Value of x = 10

2) Valye of x = -5

3) Valye of x = -6

Step-by-step explanation:

Concept :

Here, we will use the below following steps to find a solution using the transposition method:

• Step 1 :- we will Identify the variables and constants in the given simple equation.
• Step 2 :- then we Simplify the equation in LHS and RHS.
• Step 3 :- Transpose or shift the term on the other side to solve the equation further simplest.
• Step 4 :- Simplify the equation using arithmetic operation as required that is mentioned in rule 1 or rule 2 of linear equations.
• Step 5 :- Then the result will be the solution for the given linear equation.

$\begin{gathered}\end{gathered}$

Solution :

1) 3x - 5 = 25

$\twoheadrightarrow{\sf{3x - 5 = 25}}$

$\twoheadrightarrow{\sf{3x = 25 + 5}}$

$\twoheadrightarrow{\sf{3x = 30}}$

$\twoheadrightarrow{\sf{x = \dfrac{30}{3} }}$

$\twoheadrightarrow{\sf{x = \cancel{\dfrac{30}{3}}}}$

$\twoheadrightarrow{\sf{x = 10}}$

$\star{\underline{\boxed{\bf{\red{x = 10}}}}}$

Hence, the value of x is 10.

$\begin{gathered}\end{gathered}$

2) -4x + 6 = 26

$\twoheadrightarrow{\sf{ - 4x + 6= 26}}$

$\twoheadrightarrow{\sf{ - 4x= 26 - 6}}$

$\twoheadrightarrow{\sf{ - 4x= 20}}$

$\twoheadrightarrow{\sf{x= \dfrac{20}{ - 4}}}$

$\twoheadrightarrow{\sf{x= \cancel{\dfrac{20}{ - 4}}}}$

$\twoheadrightarrow{\sf{x= - 5}}$

$\star{\underline{\boxed{\bf{\red{x = - 5}}}}}$

Hebce, the value of x is -5.

$\begin{gathered}\end{gathered}$

3) 7x - 8 = -50

$\twoheadrightarrow{\sf{7x - 8 = - 50}}$

$\twoheadrightarrow{\sf{7x = - 50 + 8}}$

$\twoheadrightarrow{\sf{7x = - 42}}$

$\twoheadrightarrow{\sf{x = \dfrac{ - 42}{7} }}$

$\twoheadrightarrow{\sf{x = \cancel{\dfrac{ - 42}{7}}}}$

$\twoheadrightarrow{\sf{x = - 6}}$

$\star{\underline{\boxed{\bf{\red{x = - 6}}}}}$

Hence, the value of x is -6.
