5+-2x=2x+-5
5=4x+-5 (add 2x to both sides)
10=4x (add 5 to both sides)
10/4=x (divide both sides by 4)
30 and 13
x-y=17 and x+y=43
x=17+y and x=43-y, so 17+y=43-y
so y=13
43-13=30, so x=30 and y=13
15*0.07= 1.05 so 7% of 15 is 1.05. we add this to the total so 7% tax is going to be a price of $16.05
Answer:
315 divide by 7 nevermind
Step-by-step explanation:
Simplify, <em>7(2x+y)+6(x+5y).</em>
<em>a:</em> <em>20x+37y</em>
<em> (7 • (2x + y)) + 6 • (x + 5y)
</em>
<em>Step 2 :
</em>
<em>Equation at the end of step 2 :
</em>
<em> 7 • (2x + y) + 6 • (x + 5y)
</em>
<em>Step 3 :
</em>
<em>Final result :
</em>
<h3><em> </em>
<em> 20x + 37y</em></h3>
