The answer is B. 7(5+9)=7x+(7)(9) Simplify both sides of the equation. 98=7x+63 Flip the equation. 7x+63=98 Subtract 63 from both sides. 7x+63−63=98−63 7x=35 Divide both sides by 7. 7x7=357 Answer: x=5

I made the blank spot x if that's okay for your assignment. Simplify 8×63 to 504 504=8x+8×3 Simplify 8×3 to 24 504=8x+24 Subtract 24 from both sides 504−24=8x Simplify 504−24 to 480 480=8x Divide both sides by 8 4808=x Simplify 4808 to 60 60=x Switch sides x=60 Answer is 60. Double checking: Let x=60 8×63=8×60+8×3 Simplify 8×63 to 504 504=8×60+8×3 Simplify 8×60 to 480 504=480+8×3 Simplify 8×3 to 24 504=480+24 Simplify 480+24 to 504 504=504
