Answer:
<u>r=85</u>
Let's solve your equation step-by-step:
−6(r−98)=78
<em>Step 1: Simplify both sides of the equation</em>
−6(r−98)=78
(−6)(r)+(−6)(−98)=78<em>(Distribute)</em>
−6r+588=78
<em>Step 2: Subtract 588 from both sides</em>
−6r+588−588=78−588
−6r=−510
<em>Step 3: Divide both sides by -6</em>
−6r/−6=−510/−6
r=85
Answer:
<u>r=85</u>
7x-5y=21 when x=4 from the coordinate point of (4,y)
Next,
7x-5y=21
Substitute x with 4
7(4)-5y=21
28-5y=21
Add 5 to each side
28-5y+5y=21+5y
28=21+5y
Subtract 21 to each side
28-21=21+5y-21
7=5y
Divided 5 to each side
7/5=5y/5
y=7/5
Or
y=1 2/5
Check:
7x-5y=21
Substitute x with 4 and y with 7/5
7(4)-5(7/5)=21
28-7=21
21=21. As a result, (4,7/5) is your correct answer. Hope it help!
