Answer:
x = 83.2
Step-by-step explanation:
Let the unknown number be x
-90 * (x - 83) = x + (-99)
-90x + 7470 = x - 99
Subtract x from both sides
-90x - x + 7470 = x - x - 99
-91x + 7470 = -99
Subtract 7470 from both sides
-91x + 7470 - 7470 = -99 -7470
-91x = -7569
Divide both sides by -91
x = 83.2
Answer:
It would be 8p+4
Step-by-step explanation:
8y - 3 = 6y + 17 (add 3 to each side)
8y = 6y + 17 + 3
8y = 6y + 20 (subtract 6y from each side)
8y - 6y = 20
2y = 20 (divide 2 from each side)
2y/2 = 20/2
y = 10
The answer is y = 10
Answer:
Step-by-step explanation:
j + d = 895
j = d + 177
<u>Let us substitute the second equation into the first one for j.</u>
So the <u>first equation can be rewritten</u> as (d + 177) + d = 895
=> 2d + 177 - 177 = 895 - 177
=> 2d = 718
=> 2d/2 = 718/2
=> <u>d = 359</u>
=> j = 359 + 177
=><u> j = 536</u>
<u>Checking your answer:</u>
j + d = 536 + 359 = 895
