What is 15 equals 30-3x?
15=30-3x 15-30=3x -15=3x -15/3=x -5=x
What if linear equations starts with a negative?
Either move the negative over to the other side to become positive, or divide the entire equation by -1 to get it to a positive. Example: -3x + 12 = 30 Move the -3x over to get 12 = 30 + 3x 12 - 30 = 3x - 18 = 3x - 6 = x OR Divide by -1 to get 3x - 12 = - 30 3x = - 30 + 12 3x = -18 x = -6
What is 3x plus 6 equals 30?
3x + 6 = 30 Therefore, 3x = 24 x = 24/3 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
How to find elimination method for 3x - 4y equals 30 and 3x plus 2y equals 6?
Subtract: 3x - 3x - 4y - 2y = 30 - 6 ie -6y = 24 so y = -4 and x = 14/3
What is the answer to y equals 3x 3x plus 4y equals 30?
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
What is 15 equals 30-3x?
15=30-3x 15-30=3x -15=3x -15/3=x -5=x
-3x plus 6 equals -30?
-3x + 6 = -30 -3x = -30 - 63x = 36x = 36/3Therefore, x = 12.
What if linear equations starts with a negative?

What is 3x plus 6 equals 30?
3x + 6 = 30 Therefore, 3x = 24 x = 24/3 x = 8
X plus 30 equals 3x-50 solve for x?
x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40
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
What Is The Answer To 3x plus 12 42?
3x + 12 = 42 3x = 30 x = 10
How do you solve 13-3x equals 43?
13-3x = 43 -3x = 43-13 -3x = 30 x = -10
What is 3x 2 5x?
30.
What is 3x-2 equals 88 find x?
x is 30 to work it out- 3x 30=90 90-2=88
What is the value of x wen 3x-520 30?
If you mean: 3x-520 = 30 then the value of x is 183 and 1/3
