After substituting, what is the first step when evaluating 4y+9/7 when y=8

kenny6666 [7]

Answer:

multiply 4 and 8 to get 32

Step-by-step explanation:

After substituting, the expression is ...

4·8 +9/7

The order of operations tells you to do multiplication and division before addition and subtraction. You do them left-to-right. The multiplication on the left is 4·8, so you do that first. The result is ...

32 + 9/7

Now, you can do the division:

32 + (1 2/7)

And, finally, the addition:

33 2/7

___

Or, you could skip the division and go straight to adding a whole number and a fraction:

(32·7 +9)/7 = (224+9)/7 = 233/7

What is the solution to the system of equations below?

kifflom [539]

Answer:

(-5,-14)

Step-by-step explanation:

To find the solution of the system of two equations

$\left\{\begin{array}{l}y=4x+6\\y=2x-4\end{array}\right.$

equate right sides of these two equations:

$4x+6=2x-4$

Rewrite terms with x into the left side and without x into the right side:

$4x-2x=-4-6\\ \\2x=-10\ [\text{divide by 2}]\\ \\x=-5$

Substitute x=-5 into the first equation:

$y=4\cdot (-5)+6=-20+6=-14$

The solution is (-5,-14)
