Question

Given h(x)=-4x-5, solve for x when h(x)=7.

Answer 1

Given h(x) = -4x - 5, t

The value of x when h(x)=7 is -3

Explanation:

h(x) is defined as -4x - 5. We set this formula equal to 7 (given), obtaining:

-4(x) - 5 = 7

By combining like terms we get:

-4x = 12, or x = -3

Answer 2

h(x) = -4x - 5

h(x) =7

equate the eqns

7 = -4x - 5

-4x = 12

x = -3.
