Let's solve your equation step-by-step.

7(4−a)=3(a−4)

Step 1: Simplify both sides of the equation.

7(4−a)=3(a−4)

Simplify:

7a+28=3a−12

Step 2: Subtract 3a from both sides.

7a+283a=3a−123a

10a+28=−12

Step 3: Subtract 28 from both sides.

10a+28−28=−12−28

10a=−40

Step 4: Divide both sides by -10.

10a/−10=−40/−10

a=4

Answer:

a=4
