Answer:

[tex]x=2[/tex]

Step-by-step explanation:

Step 1 : Distribute the 8:

[tex]8(4-x)=7x+2[/tex]          

[tex]32-8x=7x+2[/tex]

Step 2: Subtract both sides by 7x because you only want one variable:

[tex]32-15x=2[/tex]

Step 3: Subtract both sides by 32:

[tex]-15x=-30[/tex]

Step 4: Divide both sides by -15:

[tex]x=2[/tex]
