Question

3. 5x + 9 = 5 + 3x
6. 8x + 4 = 3 (x - 1) + 7
guys plz solve this ​

Answer 1

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

3.5x+9=5+3x

Step by step Explanation

=>5x+9=5+3x

Now , firstly making Variable terms together and constant term together.

Note: when we shift 3x to left side it's sign gets changed to -ve . Similarly, 9 will be substracted from 5 on the other side.

=>5x-3x=5-9

=>2x=-4

=>x= -4 ÷ 2

=>x= -2

x= -2

check

=>5x+9=5+3x

=>5(-2)+9=5+3(-2)

=>-10+9=5-6

=> -1 = -1( verified)

6.8x+4=3(x-1)+7

expanding the terms and removing the brackets:

=>8x+4=3x-3+7

making Variable and constant terms together.

=>8x+4=3x+4

=>8x-3x=4-4

=>5x=0

=>x=0

x=0
