Answer:
he called 1 page and 1/4
Step-by-step explanation: so 5/8+5/8=10/8 sooo.. simpify that and get 1 1/4
1 1/4
Answer:
(There's a confusion here, is x 2 x times 2? The answer and explanation are based on x multiply by 2)
y = -8
Step-by-step explanation:
Substitution Method-
y = x 2 - 4
x = -2
y = (-2) 2 - 4
PEMDAS - parentheses; exponents; Multiplication & Division; Addition & Subtraction
we are going to multipl -2 and 2 together ---> -4
y = -4 - 4
Same sign add, different sign subtract.
Same sign keep the sign, different sign keep the larger.
y = -8

Thank you,
Have a great day!
Answer:
x = 2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 8x from both sides.
Step 3: Add 4 to both sides.
Step 4: Divide both sides by 4.
You have to get a variable by itself like in here... Y is itself so in the other equation or we can say second one you just have to sub it in... Like
2x+5(-3x-2)=16
2x-15x-10=16
Now you just have to subtract 2 from 15, because of the same variable that is (x)
So -13x-10=16
Take 10 to the other side means add from the both sides, that will get you at
-13x=26
So now x= -2
Remember you added because it was -10 if it would be a positive 10 then you have to subtract it from both of the sides but since here it was negative so you just added them up
Hope i helped
It is impossible to solve for both variables without a second equation.
