What is 5x equals 4x plus 7?
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
How do you solve the linear system negative 5x plus 3y equals 51 and y equals 10x minus 8 with substitutions?
5x+3y = 51 y = 10x-8 Substituting the bottom equation into the top equation: 5x+3(10x-8) = 51 5x+30x-24 = 51 5x+30x = 51+24 35x = 75 Divide both sides by 35 to find the value of x: x = 75/35 = 15/7 in its lowest terms. Substitute the value of x into the original equations to find the value of y: So: x = 15/7 and y = 94/7
What is 8 2x 7-5x?
It is 56-10x
How do you do 24 equals 7x plus 5x?
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
How do you solve that problem 4x-3-5x plus 7 equals 6?
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
What is the answer to 10x plus 7 equals 5x plus 32?
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
What is 10x plus 7 equals 5x plus 22?
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
What is 3x-7 equals 5x plus 13?
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
What is 7 plus 5x plus 10 plus 10x equals -58?
15x = -75, x = -5
-5x plus 12 plus 2x equals 24-10x?
12 - 3x = 24 - 10x so 7x = 12 making x = 12/7 or one and five-sevenths.
What is 5x equals 4x plus 7?
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
8x-7 plus 2x equals 6 plus 5x plus 2?
8x-7 plus 2x equals 6 plus 5x plus 2?
6-x plus 12 equals 10x plus 7 how much x equals?
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
What is the answer of 5x-7 equals 2 x plus 3-x?
5x - 7 = 2x + 3 - x5x = x + 104x = 10x = 2.5Check It!5(2.5) - 7 = 2(2.5) + 3 - (2.5)12.5 - 7 = 5 + 0.55.5 = 5.5 Correct!
What is X2 plus 10x plus 21 equals?
