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
