Work:
-6(x + 1) + 4 = 16 Distribute the -6
-6x - 6 + 4 = 16 Simplify
-6x - 2 = 16 Add 2 to both sides
-6x = 18 Divide -6 by both sides
x = -3
Check:
-6(-3 + 1) + 4 = 16
-6(-2) + 4 = 16
12 + 4 = 16
16 does = 16
Answer:
x = -3

-6(x + 1) +4 = 16
-6x - 6 + 4 = 16
-6x -2 = 16
-6x =18
x = -3
In the first line, use the distributive property to multiply -6 and what's in the parentheses. Then, add the constants (numbers without variables) together, which gives you -2. Do the opposite operatioon, adding, to get rid of the -2 from the left side, and add it on the right. Then, just evaluate, to get the answer of -3.

-6x — 6 + 4 = 16
-6x — 2 = 16
-6x = 18
x = -3

-6*X + -6*1 +4 = 16
so it's
-6x -6 + 4= 16
cancell it
-6x -2 = 16
add two to both side
-6X = 18
X = -3

you should learn how to do this problem on your own since you won't be able to get on y/a and ask for help during a test. this information was probably taught in class and its in your book
