Let's solve this problem step by step.
−2(1−3x)=22−3(x−13)
Step 1: Simplify both sides of the equation.
(−2)(1)+(−2)(−3x)=22+(−3)(x)+(−3)(−13)(Distribute)
−2+6x=22+−3x+39
6x−2=(−3x)+(22+39)(Combine Like Terms)
6x−2=−3x+61
Step 2: Add 3x to both sides.
6x−2+3x=−3x+61+3x
9x−2=61
Step 3: Add 2 to both sides.
9x−2+2=61+2
9x=63
Step 4: Divide both sides by 9.
9x/9=63/9
So, the answer to this problem is x=7.
Answer:
560x^3y^4.
Step-by-step explanation:
The (r+1)th term of (a + b)^r = nCr a^(n-r) b^r
We want the fifth term so r = 5 - 1 = 4:
(4 + 1)th term = 7C4 x^(7-4) (-2y)^4
= 35x^3 16y^4
= 560x^3y^4.
