Given these are like terms you can add them together as shown, leaving you with just 1k
However I wonder if you are missing a part of the problem
X/25 + 89 = 81
x/25 = 81 - 89
x/25 = - 8
x = -8 * 25
x = - 200
The first one is true
I also believe the 3rd one is true.....u just forgot to put the " / " .
Answer:
h = 430
Step-by-step explanation:
1290 = h/10 + h/5 Make h/5 into something that is something / 10
1290 = h/10 + 2h/(5*2) Clean up the brackets.
1290 = h/10 + 2h/10 Add the right.
1290 = 3h/10 Multiply both sides by 10
1290*10 = 10(3h/10)
12900 = 3h Divide both sides by 3
h = 430
multiply all terms in the second equation by 2 to get the coefficient on the y variable to be -6.
