Answer:
2<em>x= 1
/2
y+ 2</em>
Step-by-step explanation:
Solve for x.
<em>2x−y=4</em>
Add y to both sides.
<em>2x−y+y=4+y
</em>
<em>2x=y+4</em>
Divide both sides by 2.
<em>2x
/2 = y+4
/2</em>
<em>x=
1/
2
y+2</em>

PEMDAS
Your question was how. teehee
No Jane is not correct she has 25 cents where john has 30 cents
Answer:
x= -13
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 1 • 13 = 13
Step-2 : Find two factors of 13 whose sum equals the coefficient of the middle term, which is 14 .
-13 + -1 = -14
-1 + -13 = -14
1 + 13 = 14 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 1 and 13
x2 + 1x + 13x + 13
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+1)
Add up the last 2 terms, pulling out common factors :
13 • (x+1)
Step-5 : Add up the four terms of step 4 :
(x+13) • (x+1)
Which is the desired factorization
