What is the system of equations set in order pairs 3x plus 4y equals 38 5x - 5y equals -30?
Simultaneous equations.
-31x -18 plus 3x equals 38?
-2
What does x equal in the equation 3x plus 7 equals 37?
Ten. That means 3x equals 30, and 30 divided by three is ten.
What is 3x plus 6 equals 30?
3x + 6 = 30 Therefore, 3x = 24 x = 24/3 x = 8
-3x plus 40 equals 38?
-3x + 40 = 38 Subtract 40 from both sides: -3x = -2 Multiply both sides by -1: 3x = 2 Divide both sides by 3: x = 2/3

Given ABCD equals 38 and equals 3x plus 4 find the value of x?
ANSWER 5 EXPLANATION The diagonals bisect each other so, AE=CE This implies that 3x+4+3x+4=38 6x+8=38 Group similar terms 6x=38-8 6x=30 x=5
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)
-3x plus 6 equals -30?
-3x + 6 = -30 -3x = -30 - 63x = 36x = 36/3Therefore, x = 12.
What does x equal in the equation 3x plus 7 equals 37?
Ten. That means 3x equals 30, and 30 divided by three is ten.
What is 3x plus 6 equals 30?
3x + 6 = 30 Therefore, 3x = 24 x = 24/3 x = 8
3x plus 7 equals 37 x equals?
3x+7=37 -7 -7 3x=30 /3 /3 x=10
X plus 30 equals 3x-50 solve for x?
x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40
38 4 plus 3 plus 7-3x?
38*4 + 3 + 7 - 3x = 162 - 3x
-3x plus 40 equals 38?
-3x + 40 = 38 Subtract 40 from both sides: -3x = -2 Multiply both sides by -1: 3x = 2 Divide both sides by 3: x = 2/3
What is the x and y coordinates of these equations y equals 3x and 4x plus 2y equals 30?
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
