7+10+(-6x)=17-6x
Which ordered pair is the solution to the system of equations below using the substitute method y 6x-4 y 7x-7?
If you mean: y = 6x-4 and y = 7x-7 then by substitution x = 3 and y = 14
7 plus 7x--2x plus 3?
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
6x² plus 7x equals 5?
6x2 + 7x = 56x2 + 7x - 5 = 0x =[ -7 ± √[72 - 4(6)(-5)] ]/2(6)x = [-7 ± √(49 + 120)]/12x = (-7 ± √ 169)/12x = (-7 ± 13)/12x = (-7 + 13)/12 or x = (-7 - 13)/12x = 6/12 = 1/2 orx = -20/12 = - 5/3
4x plus 7 equals 6x plus -7?
4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
How do you solve 7 plus x equal sign 0 minus 6x and both sides have to be equal?
The question is 7+x=0-6x 1. First, isolate x, which is 7+x-7+6x=0-6x+6x-7 2. Second, simplify, which is 7x=-7 3. Divide both side by 7 to isolate x, which is 7x/7=-7/7 4. The answer is x=-1
How do you simplify 6x plus x?
Perform the addition. You know that 6 cows plus one cow is 7 cows, 6 kittens plus 1 kitten is 7 kittens, and 6 computers plus 1 computer is 7 computers. It should not surprise you to discover that [ 6x + 1x ] = 7x .
What is -6x plus 2 equals 7x plus 9?
x=-7/13
What is 7x plus 8-x-7 in simplest form equal?
7x+8-x-7 6x+1
Simplify the variable expression 6x plus 1 plus 7 - 3?
Simple,its just like this: 6x+1+7-3 =6x+8-3 =6x+5
How do you solve x plus 3 plus 6x plus 9 equals 0?
If: x+3+6x+9 = 0 then 7x+12 = 0 So: 7x = -12 and x = -12/7
-6x plus 72 equals x?
-6x+72=x then -7x=-72 so x=72/7
What is the factorization of the trinomal below -x2 plus x plus 42?
-x2 + x + 42= -x2 + 7x - 6x + 42= 7x - x2 + 42 - 6x= x(7 - x) + 6(7 - x)= (7 - x)(x + 6)
6x-12 plus 4x plus 5?
6x - 12 + 4x + 5 = 06x + 4x = 12 - 510x = 7x = 7/10
What is the answer to -8 plus 7 multiply 6x plus 3 equals -7x-5-1?
-8 + 7(6x) + 3 = -7x - 5 - 1-8 + 42x + 3 = -7x - 5 - 142x - 8 + 3 = -7x - 5 + (-1)42x - 5 = - 7x - 642x + 7x - 5 + 5 = - 7x + 7x - 6 + 549x = -149x/49 = -1/49x = -1/49
Simplify the variable expression which is 6x plus 1 plus 7-3x.?
3x + 8
What is the answer to 7 equals 7x plus 2?
Step 1. 7 = 7x +2 Step 2. subtract 2 from both sides: 7 - 2 = 7x + 2 - 2 and simplify: 5 = 7x Step 3. divide both sides by 7: (5/7) = (7x/7) and simplify 5/7 = x x = 5/7 or about 0.714285
