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]
