Question

3. So the following linear equations:
1. 5 (x+1)=25
​

Answer 1

Answer:

1. 5(x+1)=25

5x + 5 = 25

5x. = 25-5

5x. = 20

x. = 20

5

x. = 4

that's your answer

hope this will help you dear

mark as brainiest answer

give me thanks

Answer 2

Question:

Slove the following linear equations:

➝ 5(x+1)=25

Analysis:

Linear equations are equations of the first order. These equations are defined for lines in the coordinate system.

☞ An equation for a straight line is called a linear equation.

☞ The general representation of the straight-line equation is y = mx+b , where m is the slope of the line and b is the y-intercept.

Solution:

Given,

Equation → 5(x+1) = 25

$→\;{\sf{5(x+1) = 25}}$

$→\;{\sf{5x+5 = 25}}$

$→\;{\sf{5x = 25-5}}$

$→\;{\sf{5x = 20}}$

$→\;{\sf{x = \cancel{\frac{20}{5}}}}$

$→\;{\sf{x = 4}}$

AnSweR:

The Value of x is ◕➜ $\huge{\red{\bf{4}}}$

$\Large{\green{\underline{\underline{\mathcal{Verify:}}}}}$

➝ 5(4+1) = 25

➝ 5(5) = 25

➝ 25 = 25

→ LHS = RHS
