How do you simplify y equals 2x-5 and 4x-y equals 7?
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
If 4X - 7 equals 2X plus 5 what is the value of x?
(The original question was misphrased.) 4x-7 = 2x+5 resolves as 2x-7 = 5 2x = 12 x = 6
4X-5 plus 2X equals 37?
4x - 5 + 2x = 376x - 5 = 376x = 37 + 56x = 42x = 42 / 6x = 7

What is the answer to 4x-7-2x 5?
Well take your pick either 4x-7 = -28 .... -28 -2 = -30 .... -30x5 = -150 or 4x-7 = -28 .... (-2x5=-10) .... -28-10 = -38
How do you simplify y equals 2x-5 and 4x-y equals 7?
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
If 4x minus 7 equals 2x plus 5 what is x?
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
2x plus 5 equals 7-4x?
2x + 5 = 7 - 4x ie 2x + 4x = 7 - 5 ie 6x = 2 x = one third.
What is the answer to 2x plus 3 equals 4x-7?
2x + 3 = 4x - 7 <=> 4x - 7 = 2x + 3 <=> 2x = 10 <=> x = 5 - - - 2x + 3 = 4x - 7 Take the 2x from each side of the equation. 3 = 2x - 7 Get the numerals together 7 + 3 = 2x Therefore 10 = 2x Therefore 5 = x
What is (4x-5)and(2x+7) in simplest form?
Simplifying 4x + -5 = 2x + 7 Reorder the terms: -5 + 4x = 2x + 7 Solving -5 + 4x = 7 + 2x Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. -5 + 4x + -2x = 7 + 2x + -2x Combine like terms: 4x + -2x = 2x -5 + 2x = 7 + 2x + -2x Combine like terms: 2x + -2x = 0 -5 + 2x = 7 + 0 -5 + 2x = 7 Add '5' to each side of the equation. -5 + 5 + 2x = 7 + 5 Combine like terms: -5 + 5 = 0 0 + 2x = 7 + 5 2x = 7 + 5 Combine like terms: 7 + 5 = 12 2x = 12 Divide each side by '2'. x = 6 (your answer)
What is the answer to 5-4x equals 12-2x?
5-4x=12-2x isolate your x's on one side 5=12-2x+4x 5-12=-2x+4x simplify -7=2x divide by 2 x=-7/2, or x=-3.5
If 4X - 7 equals 2X plus 5 what is the value of x?
(The original question was misphrased.) 4x-7 = 2x+5 resolves as 2x-7 = 5 2x = 12 x = 6
If 4x-7 equals 2x plus 5 What is x?
4x - 7 = 2x + 5Add 7 to each side ==> 4x = 2x + 12Subtract 2x from each side ==> 2x = 12Divide each side by 2 ==> x = 6
4x plus 5 equals 2x plus 19?
4x + 5 = 2x + 19Subtract 5 from each side:4x = 2x + 14Subtract 2x from each side:2x = 14Divide each side by 2:x = 7
7x plus 6 minus 4x equals 5 plus 2x plus 7?
7x + 6 - 4x = 5 + 2x + 7 subtract 6 from both sides and combine the 5 and 7 on the right: 7x - 4x = 2x + 6 subtract 2x from both sides and combine the 7x and -4x on the left: x = 6
4X-5 plus 2X equals 37?
4x - 5 + 2x = 376x - 5 = 376x = 37 + 56x = 42x = 42 / 6x = 7
How do you solve4x-7 equals 2x plus 5 what is x?
4X - 7 = 2X + 5 subtract 2X from each side 4X - 2X - 7 = 2X - 2X + 5 2X - 7 = 5 add 7 to each side 2X - 7 + 7 = 5 + 7 2X = 12 divide both sides integers by 2 (2/2)X = 12/2 X = 6 --------------check in original equation 4(6) - 7 = 2(6) + 5 24 - 7 = 12 + 5 17 = 17 -----------checks
