If ax+3=7-bx what is x expressed in terms of a and b
1 answer:
All we want to do is get an equation with just x on one side and no x's on the other.
We can use inverse operations to accomplish this.
First, bring bx to the left side. Subtract the 3.
Factor ax+bx to x(a+b). (this is pretty much reversing the distributive property)
Divide by a+b and you are left with just x on the left side as 4/(a+b).

Answer:
The value of x for the expression is 2
Step-by-step explanation:
Given algebraic expression as :
(4 + 6 x ) =
x +
( x + 9 )
Now, solving the given expression
Or, × 4 +
× 6 x =
x +
x +
× 9
Or, +
× x =
x +
x +
or, 2 + 3 × x = +
+ 6
or, 2 + 3 × x = + 6
or, 2 + 3 × x = + 6
Or, 2 + 3 × x = x + 6
or, 3 x - x = 6 - 2
Or, 2 x = 4
∴ x =
I.e x = 2
Hence The value of x for the expression is 2 Answer
