Step-by-step explanation:
Statement that is expressed in words
Answer:
- 1, - 3, - 5
Step-by-step explanation:
Substitute n = 1, 2, 3 into the rule, that is
a₁ = - 2(1) + 1 = - 2 + 1 = - 1
a₂ = - 2(2) + 1 = - 4 + 1 = - 3
a₃ = - 2(3) + 1 = - 6 + 1 = - 5
x = 3 - (3×6) + 2. We perform the operation in the bracket first.
x = 3 - 18 + 2
x = -15 + 2 = 2 -15 = -13
x = -13
Answer:
x=9/2
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+4(−x−2)=−5x+2(x−1)+12
Step 1: Simplify both sides of the equation.
5x+4(−x−2)=−5x+2(x−1)+12
5x+(4)(−x)+(4)(−2)=−5x+(2)(x)+(2)(−1)+12 (Distribute)
5x+−4x+−8=−5x+2x+−2+12
(5x+−4x)+(−8)=(−5x+2x)+(−2+12) (Combine Like Terms)
x+−8=−3x+10
x−8=−3x+10
Step 2: Add 3x to both sides.
x−8+3x=−3x+10+3x
4x−8=10
Step 3: Add 8 to both sides.
4x−8+8=10+8
4x=18
Step 4: Divide both sides by 4.
4x/4=18/4
x=9/2
Answer:
x=5
Step-by-step explanation:
add 5 to both sides
-20+5 = -3x
-15=-3x (divide)
x=5
