65 total test items were on the test.
Step 1: Simplify both sides of the equation.
−(5−(a+1))=9−(5−(2a−3))
−(5−(a+1))=9+−1(5−(2a−3))(Distribute the Negative Sign)−(5−(a+1))=9+(−1)(5)+−1(−2a)+(−1)(3)−(5−(a+1))=9+−5+2a+−3a+−4=9+−5+2a+−3(Distribute)a−4=(2a)+(9+−5+−3)(Combine Like Terms)a−4=2a+1a−4=2a+1Step 2: Subtract 2a from both sides.a−4−2a=2a+1−2a−a−4=1Step 3: Add 4 to both sides.−a−4+4=1+4−a=5Step 4: Divide both sides by -1.−a−1=5−1a=−5

Answer:
x = 6
Step-by-step explanation:
Use -8 in place of f(x) and solve the resulting 2-step linear equation in the usual way.
-8 = -3x +10
-18 = -3x . . . . . . . . step 1, subtract 10
6 = x . . . . . . . . . . . step 2, divide by the coefficient of x
