Question

4x+12=20-3x solve it with process ​

Answer 1

Step-by-step explanation:

4x+3x+12-20=0

{By grouping variables and constants}

{Solve it}

7x-8=0

This is only the answer.

More simplification can be done only when we know x value

Answer 2

$\bold{4x+12=20-3x }$

$\bold{4x+12= - 3x + 20 }$

$\bold{4x+12 - 12= - 3x + 20 - 12 }$

$\bold{4x = - 3x + 8}$

$\bold{4x + 3x = - 3x + 8 + 3x}$

$\bold{7x = 8}$

$\bold{ \frac{7x}{7} = \frac{8}{7} }$

$\bold{ x = \frac{8}{7} }$
