Y= -2x-5
Y=8x+5
^^ those two equations are basically the same so you put them side by side like:
-2x-5=8x+5
Subtract 5 on both sides which leads to:
-2x-10=8x
Add 2x both sides:
-10=10x
Divide both sides by 10
-1=x
Step-by-step explanation:
number of the total cookies ÷ the nber her brother ate
6÷2=3
6 - x = 2(x - 6)
the first step, following PEMDAS, is to distribute the 2 to the inside of your parentheses:
6 - x = 2x - 12 ... subtract 2x
6 - 3x = -12 ... subtract 6
-3x = -18 ... divide by -3
x = 6 is the answer
