Answer:
219
Step-by-step explanation:
a is the number needed to add from the first to the second which is 4(must be constant)
b is the term zero means 15-a which is 15-4=11
I included the formula and the answer
The answer is 3
The question is wrong tho its not the same as the picture
Its not
16x + 181 = 12x
Its
6x +18= 12x
And the solution is
-18 on bothes sides then we have left 6x=12x-18
Then we take -12x on both sides
6x-12x= -18 6x-12x = -6x
-6x=-18
The u divede -18 = -6x
———
-6 -6
Then u get -18/-6= 3 and -6x/-6 = x
x = 3
2x+3=3x-1
2x+2=3x
x=2
total value of the equation is 5
