Given the equations below what is the value of ab?
10b-9a=6
b-a=1

12

Step-by-step explanation:

Adding a to both sides of the second equation we get b = a+1

Substituting this in we get

10a + 10 - 9a=6

a +10 =6

a=-4

Putting this back in to the second one we get b+4=1

B=-3

-4*-3=12

One day every tear that falls will be wiped by His hand

We will see the promised land, mmm

Hallelujah, there will be healing

From this heartbreak we've been feeling

We'll sing in the darkest night

'Cause we know that the light will come

And there will be healing, hallelujah

Step-by-step explanation:
