Let's first simplify the expression 5a - 3a−10b3a - 10b3a−10b:
5a - 3a−10b3a - 10b3a−10b = 5a - 3a + 10b= 2a + 10b
Given that a + 5b = 1.7, we can rewrite the equation as:
a = 1.7 - 5b
Now, substitute a = 1.7 - 5b into the expression 2a + 10b:
21.7−5b1.7 - 5b1.7−5b + 10b= 3.4 - 10b + 10b= 3.4
Therefore, 2a + 10b = 3.4.
