Presumably this is a simultaneous equation question in the form of:
3x+6y = 48
-5x+6y = 32
Subtract the bottom equation from the top equation in order to eliminate y. Note that 3x - - 5x is equal to + 8x:
8x = 16
Divide both sides by 8 to find the value of x:
x = 2
Substitute the value of x into the original equations to find the value y:
Therefore: x = 2 and y = 7

When using substitution What is x and y for 3x plus 6y equals 48 -5x plus 6y equals 32?
3x + 6y = 48 .... Eq.1-5x + 6y = 32 .... Eq.2 .... in another way 6y = 5x + 32Put the value of Eq.2 in Eq. 13x + 5x + 32 = 488x = 48 - 328x = 16x = 16/8 ...... X = 2To find the value of Y put the value of X in Eq.26y = 5x + 326y = 5(2) + 326y = 10 + 326y = 42y = 42/6 ...... Y + 7
What is the answer for 3x plus 6 equals 54?
This is elementary stuff: 3x + 6 = 54 Subtract 6 from each side: 3x = 48 Divide each side by 3: x = 16.
48 plus 48 plus 48 equals?

What is x if 3X plus 13 equals 61-3X?
3x + 13 = 61 - 3x : add 3x to both sides 6x + 13 = 61 : deduct 13 from both sides 6x = 48 : divide both sides by 6 x = 8
What is 5x-30 equals 3x plus 2?
5X - 30 = 3X + 2 subtract 3X from both sides 5X - 3X - 30 = 3X - 3X + 2 2X - 30 = 2 add 30 to each side 2X - 30 + 30 = 2 + 30 2X = 32 divide both sides integers by 2 (2/2)X = 32/2 X = 16 -----------------check in original equation 5(16) - 30 = 3(16) + 2 80 - 30 = 48 + 2 50 = 50 checks
3x plus 12 equals x plus 48?
3x+12=x+48: 3x-x=-12+48 2x=36 x=18
3x plus 5y equals 48 -3x plus 5y equals 12Solve the system of equations Enter your answer as an ordered pair?
3x+5y=48 5y=48-3x-3x+5y=12 -3x+(48-3x)=12-6x=-36x=65y=48-3(6)5y=30y=6(6,6)
3x plus 10x-48 equals 0?
3x + 10x - 48 = 0 13x = 48 x = 3.692307692
Is 16 plus 32 equals 52?
No. 16 + 32 = 48
When using substitution What is x and y for 3x plus 6y equals 48 -5x plus 6y equals 32?
3x + 6y = 48 .... Eq.1-5x + 6y = 32 .... Eq.2 .... in another way 6y = 5x + 32Put the value of Eq.2 in Eq. 13x + 5x + 32 = 488x = 48 - 328x = 16x = 16/8 ...... X = 2To find the value of Y put the value of X in Eq.26y = 5x + 326y = 5(2) + 326y = 10 + 326y = 42y = 42/6 ...... Y + 7
What is X2 plus 8x 48 equals 0?
x² + 8x - 48 = (x + 12)(x - 4) x² + 8x + 48 = (4+(√32)i)(4-(√32)i)
What is the answer for 3x plus 6 equals 54?
This is elementary stuff: 3x + 6 = 54 Subtract 6 from each side: 3x = 48 Divide each side by 3: x = 16.
What is the solution set of 3X-5 equals 48?
3x - 5 = 48 So 3x = 53 and x = 53/3 = 17.66...
What is 12 plus 12 plus 12 plus 12 equals?
12 + 12 = 24. 24+12=32. 32 + 12 = 44
What is 48 plus 32?
48 + 32 = 80
48 plus 48 plus 48 equals?
144
What is x if 3X plus 13 equals 61-3X?
3x + 13 = 61 - 3x : add 3x to both sides 6x + 13 = 61 : deduct 13 from both sides 6x = 48 : divide both sides by 6 x = 8
