Answer: -2

Step-by-step explanation: It is long

Step 1: Simplify both sides of the equation.

10(x+3)−(−9x−4)=x−5+3

10(x+3)+−1(−9x−4)=x−5+3(Distribute the Negative Sign)

10(x+3)+−1(−9x)+(−1)(−4)=x−5+3

10(x+3)+9x+4=x−5+3

(10)(x)+(10)(3)+9x+4=x+−5+3(Distribute)

10x+30+9x+4=x+−5+3

(10x+9x)+(30+4)=(x)+(−5+3)(Combine Like Terms)

19x+34=x+−2

19x+34=x−2

Step 2: Subtract x from both sides.

19x+34−x=x−2−x

18x+34=−2

Step 3: Subtract 34 from both sides.

18x+34−34=−2−34

18x=−36

Step 4: Divide both sides by 18.

18x/18 = −36/18

x=−2
