Answer:
z = 46/13
Step-by-step explanation:
Step 1: Write equation
z + 6 ÷ 13 = 4
Step 2: Solve for <em>z</em>
- Rewrite: z + 6/13 = 4
- Subtract 6/13 on both sides; z = 46/13
Step 3: Check
<em>Plug in z to verify it's a solution.</em>
46/13 + 6/13 = 4
52/13 = 4
4 = 4
Answer:
X = -5
Step-by-step explanation:
-6x + 18 = 7 - (4x + 9)
first we simplify the parentheses.
distribute the invisible number one created by the negative sign in front of the parentheses to get -6x + 18 = 7 - 4x - 9
then simplify further by subtracting 9 from the right side, leaving you with
-6x + 18 = -2 - 4x
next, add 2 to both sides to isolate the variable.
-6x + 20 = -4x
then, to isolate the variable further add 6x to both sides.
20 = -4x
divide both sides by -4 to isolate the variable
-5 = x
so, x = -5
Answer:
-7
Step-by-step explanation:
f(x)=4x+5
Let x =-3
f(-3)=4*-3+5
Multiply
f(-3)=-12+5
Add
f(-3) = -7
