<u><em>Answer: x=-8 and -8=x. *The answer should have negative sign.*</em></u>
Step-by-step explanation:
distributive property: a(b+c)=ab+ac
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
subtract 4 both sides of an equation.
-12x+4-4=100-4
simplify.
-12x=96
divide by -12 both sides of an equation.
-12x/-12=96/-12
96/12=8
96/8=12
8*12=96
12*8=96
It change positive to negative sign.
x=-8
Hope this helps!
Thanks!
Have a great day!
Answer:
yes
Step-by-step explanation:
the x numbers do not repeat.
The answer is Step 2.
The exponential equation is: 3ˣ⁺¹ = 15.
Step 1: log3ˣ⁺¹ = log15
Step 2: (x + 1) * log3 = log15
Step 3: x + 1 = log 15 / log 3
Step 4: x + 1 = 1.18 / 0.48
Step 5: x + 1 = 2.46
Step 6: x = 2.46 - 1
Step 7: x = 1.46
I think it means like mark an answer maybe if not I'll look it up for you
