Let's solve your equation step-by-step

7(x-3)=4(x+5)

Step 1:Simplify both side of the equation

7(x-3)=4(x+5)

(7)(x)+(7)(-3)=(4)(x)+(4)(5) (Distribute)

7x+-21=4x+20

7x-21=4x+20

Step 2:Subtract 4x from both sides

7x-21-4x=4x+20-4x

3x-21=20

Step 3: Add 21 to both sides

3x-21+21=20+21

3x=41

Step 4: Divide both sides by 3

3x/3 =41/3

Answer: x=41/3
