Question

find the solution of the equation 5a+3=2a-3

what will be the solution of its equation 7+6x=-5

please koi answer bata dijiye aaj mera maths ka exam hai please​

Answer 1

Answer

(1).

➡ 5a+3=2a-3

➡ 5a - 3a = -3 - 3

➡2a = -6

➡a = -6/2

➡a = -3

(2)

➡7+6x=-5

➡ 6x = -5 - 7

➡6x = -12

➡x = -12/6

➡x = -2

Answer 2

$\red\bigstar$Answer:

• a = (-2)
• x = (-2)

$\pink\bigstar$ Given:

1. 5a + 3 = 2a - 3
2. 7 + 6x = (-5)

$\blue\bigstar$ To find:

1. The value of a
2. The value of x

$\green\bigstar$ Solution:

$\star$ Value of a in : 5a + 3 = 2a - 3

Here,

5a + 3 = 2a - 3

$\implies$5a - 2a = (-3) - 3

$\implies$3a = (-6)

$\implies$ a = (-6)/3

$\implies\boxed{a \: = \: (-2)\:}$

$\therefore$ a = (-2)

$\star$ Value of x in : 7 + 6x = (-5)

Here,

7 + 6x = (-5)

$\implies$ 6x = (-5) - 7

$\implies$ 6x = (-12)

$\implies\boxed{x\: =\: (-2)\:}$

$\therefore$ x = (-2)
