Answer:
55
Step-by-step explanation:
Divide 715/13 and the quotient is the answer.
<u>Answer:</u> x = 1/5 and y= -7/5
Step-by-step explanation: Let's solve your system by elimination.
Multiply the first equation by -3,and multiply the second equation by 1.
-3 (x - 2y = 3)
1 (3x - y = 2)
Becomes:
-3x + 6y = -9
3x -y = 2
Add these equations to eliminate x:
5y = -7
Then solve 5y = -7
5y/7 = -7/5
y = -7/5
Now that we‘ve found y, let’s plug it back in and solve for x.
Write down an original equation:
x - 2y = 3
<h3>
Substitute -7/5 for y in x - 2y = 3:</h3><h3>
x - 2 (-7/5) = 3</h3><h3>
x + 14/5 = 3</h3><h3>
x 14/5 + -14/5 = 3 + -14/5 (Add (-14)/5 to both sides)</h3><h3>
x = 1/5</h3><h3><u>
Answer: </u></h3><h3>x = 1/5 and y = -7/5</h3><h3 /><h3 /><h3 />
All answers are the pic.
When you are lining up the ratios, make sure they are aligning each other with the same unit.
P: Parenthesis
E: Equation
M:Multiplication
D: Division
A : addition
S: Subtraction
So first you need to divide because it is before so you divide 18 by 6 which is 3 then you subtract (31 - 3) which gives you 28
answer : 28
