Tip: Go step-by-step
Let the number = x
Eight times the difference between a number and seven.. = 8(x-7)
is the same as... =
the number increased by 4.. x+4
8(x-7)=x+4
Distribute
8x-56=x+4
Subtract x from both sides
7x-56=4
Add 56 to both sides
7x=60
x=60/7
The answer is no solution because when you solve the equation
3(x+4)=3x+4
3x +12=3x +4
-3x -3x
You get an answer of 12=4 which is not true so there cannot be a solution to this equation
The answer is A no solution
