7a=12a+10 /-12a (from both sides)
7a-12a=10
-5a=10 /: -5 (from both sides)
a= -2
(7X-2=12X-2+10
-14= -24+10
-14=-14)
Here i just added one with a few more words incase you need them, but the above answer is the exact same, all of our steps are the same too! They also added how to check your answer at the end there.
We start with the equation
7a=12a+10 ===> we want to get all the variables on one side of the equation ( which would be our "a")
So we minus 12a from both sides of the equation giving us
-5a= 10 ====> now we want a by itself so we do the opposite of multiplication which is division so we are now going to divide both sides by -5 ( remember to include your negative sign in your division)
So divide both sides by -5 which gives
a=-2

What is seven times a plus ten equals two times a?
7a + 10 = 2a 7a = 2a -10 5a = -10 a = -2
What is 4a plus 3a-4 equals 10?
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
What is the answer to A plus 18 equals 7a?
a + 18 = 7a a-a +18 = 7a-a 18 = 6a 18/6 = 6a/6 3 = a 3=a
How do you simplify this expression 12a - 6a plus a?
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
9a plus 15 equals 7a plus 9?
Collect like terms: 9a -7a = 9 - 15, ie 2a = -6, so a = -3
What is 12a - 6a plus a?
18
How do you do 7a plus 10 equals 2a?
7a+10=2a 7a+10-2a=0 5a+10=0 5a=-10 a=-2
What is seven times a plus ten equals two times a?
7a + 10 = 2a 7a = 2a -10 5a = -10 a = -2
7a plus 3 plus -a - 5 equals -16?
(7a=3)=(-a-5)=16
Evaluate a+4a+4a, plus, 4 when a=7a=7a, equals, 7?
555
7a plus 4 equals 5a plus 7?
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
Solve a over 5 plus a over 2 equals 14 over 2?
a/5 + a/2 = 14/2 2a/10 + 5a/10 = 7 7a/10 = 7 7a = 70 a = 10
Solve the equation 9a-a equals 19 plus 7a?
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
What is 4a plus 3a-4 equals 10?
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
What is the answer to A plus 18 equals 7a?
a + 18 = 7a a-a +18 = 7a-a 18 = 6a 18/6 = 6a/6 3 = a 3=a
How do you simplify this expression 12a - 6a plus a?
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
7a-17 equals 4a plus 1?
7a-17 = 4a+1 7a-4a = 1+17 3a = 18 a = 6
