Find values for a and b so that 2(3x+5)+ax=5(4x−b) is an identity equation.

Answer:

a=30 b=2 (not sure)

Step-by-step explanation:

Simplify first part : 2*3x+ 2*5= 6x+10+ax

Simplify 2nd part : 5*4x-5*b. 5x-5b

we have: 6x+10+ax=20x-5b.

we minus 6x from both sides

10+ax=14x+5b

Minus 10

ax=14x+5b-10

Divide x

a=14+5b-10

a=4+5b

divde 5

a/5= 4+b

perhaps it is 30

30/5=4+b

6=6

but i am not sure
