PLEASE HELP THIS TEST IS WORTH 3 GRADESS

a) Apply the Distributive Property

(at least this is what my teacher tells us to do...might be different in your case)

b) x = 9

Step-by-step explanation:

4(2x+3)=5x−(−4x−3)

4(2x+3)=5x+−1(−4x−3)(Distribute the Negative Sign)

4(2x+3)=5x+−1(−4x)+(−1)(−3)

4(2x+3)=5x+4x+3

(4)(2x)+(4)(3)=5x+4x+3(Distribute)

8x+12=5x+4x+3

8x+12=(5x+4x)+(3)(Combine Like Terms)

8x+12=9x+3

8x+12=9x+3

Step 2: Subtract 9x from both sides.

8x+12−9x=9x+3−9x

−x+12=3

Step 3: Subtract 12 from both sides.

−x+12−12=3−12

−x=−9

Step 4: Divide both sides by -1.

x=9
