If 5x + 6 = 10, what is the value of 10x + 3?

1 answer

To find the value of 10x + 3, we need to first solve the equation 5x + 6 = 10.

Subtracting 6 from both sides of the equation gives us:
5x + 6 - 6 = 10 - 6
5x = 4

Dividing both sides of the equation by 5 gives us:
5x/5 = 4/5
x = 4/5

Now, we can substitute the value of x into the expression 10x + 3.
10(4/5) + 3 = 8 + 3 = 11

Therefore, the value of 10x + 3 is 11.
