Answer:
Answer: x = a*y + 3
Step-by-step explanation:
To make x the subject of the equation, first, we open the bracket
4x - 12/a = y
Then cross multiply:
4x - 12 = a * y ( a*y means the product of the two variables)
Add 12 to both sides of the equation
4x = a*y + 12
Divide both sides by 4 to get the value of x
x = a * y + 12/4
x = a*y + 3
You are solving the two equations for x.

r = 4 + 7x - sx
We need to solve for x. x is only found in the right side. First, just flip the sides to find x only in the left side.
4 + 7x - sx = r
We want all terms with x on the left side, and all terms without x on the right side. Now we subtract 4 from both sides.
7x - sx = r - 4
Factor x in left side.
x(7 - s) = r - 4
Divide both sides by 7 - s.
12.
3z + 8 = 12 + 3x - z
Since x is only in the right side, flip the sides.
12 + 3x - z = 3z + 8
We need to isolate x in the left side, so subtract 12 from both sides and add z to both sides.
3x = 3z + 8 - 12 + z
3x = 4z - 4
Divide both sides by 3.
Answer:
2x^2+3x+3
Step-by-step explanation:
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).
STEP 1
The Equation at the end of step 1
(3x2 + 5x) - x2) - 2x) + 3
STEP 2
Trying to factor by splitting the middle term
2.1 Factoring 2x2+3x+3
The first term is, 2x2 its coefficient is 2.
The middle term is, +3x its coefficient is 3.
The last term, "the constant", is +3
Step-1: Multiply the coefficient of the first term by the constant 2 • 3 = 6
Step-2: Find two factors of 6 whose sum equals the coefficient of the middle term, which is 3.
-6 + -1 = -7
-3 + -2 = -5
-2 + -3 = -5
-1 + -6 = -7
1 + 6 = 7
2 + 3 = 5
3 + 2 = 5
6 + 1 = 7
Observation: No two such factors can be found !!
Conclusion: Trinomial can not be factored
Final result :
2x^2 + 3x + 3
Hope this helps!
