-4x + 10 = 42 what is the value of x

x=-8

Step-by-step explanation:

Well subtract 10 on both sides

-4x=32

Div ide -4 on both sides

x=-8

x = -8

Step-by-step explanation:

-4x + 10 = 42

       -10   -10

-4x = 32

/-4     /-4

x = -8

to check work, insert x into the normal equation

-4(-8) + 10 = 42

32 + 10 = 42

answer: the answer is ann

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
