Stepbystep explanation:
1. 4x  7 = 2x + 12, Given
2. 4x  7 + 2x = 2x + 12 + 2x, Addition property of equality
3. 6x  7 = 12, Simplification
4. 6x  7 + 7 = 12 + 7, Addition property of equality
5. 6x = 19, Simplification
6. 6x/6 = 19/6, Division property of equality
7. x = 19/6, Simplification

Answer:
The steps are :
1. [tex]4x7=2x+12[/tex]  This is Given
2. [tex]4x7+2x=2x+12+2x[/tex]  Here, addition property of equality is used.
3. [tex]6x7=12[/tex]  This step is simplification as both the LHS and RHS are being calculated and simplified.
4. [tex]6x7+ 7=12+7[/tex]  Here, again addition property of equality is applied.
5. [tex]6x =19[/tex]  This is simplification again.
6. [tex]\frac{6x}{6}=\frac{19}{6}[/tex]  Here the division property of equality is applied.
7. [tex]x=\frac{19}{6}[/tex]  This step is simplification.
