How do you solve this 4m plus 15 equals 8m-5?
4m+15=8m-5 or,4m=20 or,m=5
How do you solve 4m-4 equals 4m?
It has no solution since subtracting 4m from both sides leads to -4 = 0 which is not true.
How do you solve 5-4mdivided by 3 equals -7?
To solve for m, we must isolate m: (5-4m)/3 = -7 Multiply both sides by 3: 5-4m = -21 Subtract 5 from both sides: -4m = -26 Divide by -4: m = 13/2 = 6.5
What is the answer to -4m plus 3 equals -8?
-4m + 3 = -8 -4m = -8 -3 -4m = -11 4m = 11 m = 2.75
6m plus 5n-4m plus 7n equals?
6m + 5n - 4m + 7n = 2m + 12n
How do you solve this 4m plus 15 equals 8m-5?
4m+15=8m-5 or,4m=20 or,m=5
How do you solve 4m-4 equals 4m?
It has no solution since subtracting 4m from both sides leads to -4 = 0 which is not true.
How do you solve the problem 15 plus 4m equals -1?
15+4m=-14m=-16 (subtract 15 from both sides to isolate variable (4m))m=-4 (divide each side to isolate variable from coefficient)
How do you solve problem 4m plus 12 equals 60?
4m + 12 = 604m + 12 -12 = 60 -12 (1st subtract 12 from both sides)4m = 484m/4 = 48/4 (now divide both sides by 4 to solve for m)m = 12
How do you solve 5-4mdivided by 3 equals -7?
To solve for m, we must isolate m: (5-4m)/3 = -7 Multiply both sides by 3: 5-4m = -21 Subtract 5 from both sides: -4m = -26 Divide by -4: m = 13/2 = 6.5
What is the answer to -4m plus 3 equals -8?
-4m + 3 = -8 -4m = -8 -3 -4m = -11 4m = 11 m = 2.75
6m plus 5n-4m plus 7n equals?
6m + 5n - 4m + 7n = 2m + 12n
What is the answer to 4m-3 equals 21?
m = 6
How to solve 4m plus 5m-2n?
It can be simplified to: 9m-2n
What is the common point of these equations 2x plus 3y equals 12m and x - 3y equals -3?
It is [4m-1, (4m-2)/3]
How do you solve 3m plus m equals 88?
Well, 3m + m = 4m so 88 divided by 4= 22 there fore m =22 and 3m = 66
What expression is equivalent to 4m plus 8 plus 5M?
simplified it equals, 9m+8
