-8x plus 7 equals -7x-2?
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
What is the LCM of 7x and 8x squared?
56x2
8 x-1 equals 7x plus 2 Answer?
8x-1 = 7x+2 Add 1 to both sides: 8x = 7x+3 Subtract 7x from both sides: 1x = 3 ie x = 3
What is 3x plus 4x?
3x + 4x = 7x
How do you solve the system of equation problem in algebra 8x-10y equals 2 added with 7x-5y equals 13?
8x - 10y = 27x - 5y = 13First, we need to eliminate one of the variables. For this, we would like to have them with the same coefficient but different sign. We can do this if we multiply by -2 the second equation.8x - 10y = 2-2(7x - 5y) = -2(13)8x - 10y = 2-14x +10y = -26Now, we can add both equations, and solve for x.(8x - 10y) + (-14x + 10y) = (2) + (-26)(8x - 14x) +(-10y + 10y) = (2 - 26)-6x = - 24-6x/-6 = - 24/-6x = 4Substitute 4 for x in the first equation:8x - 10y = 28(4) - 10y = 232 - 10y = 232 - 32 - 10y = 2 - 32-10y = -30-10y/-10 = -30/-10y = 3Thus, the solution of the system is (4, 3).Check:
-8x plus 7 equals -7x-2?
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
What do you do if the solution is 8x equals 7x?
Because 8 does not = 7, there is no solution. You write No Sol. Alternatively if you simplify an equation to x = x, that would be All Solutions (any number substituted for x satisfies the equation) * * * * * Wrong! 8x = 7x DOES have a solution and that is x = 0
What is the solution of the equation 3x plus 17 plus 5x equals 7x plus 10?
3x + 17 + 5x = 7x + 10Combine (add) the 'x'-terms on the left side of the equation:8x + 17 = 7x + 10Subtract 17 from each side:8x = 7x - 7Subtract 7x from each side:x = -7
What does x equal in 8x equals 7x-7?
8x=7x-7 x=-7
How do you sinplify the expression 6x 7x-8x?
Do you mean 6x+7x-8x if so it is 5x because 13x-8x = 5x
What is the solution set of -8x plus x plus 15 equals -7x plus 12?
the empty set.
What is 8x-x?
It is: 7x
What is the real solution for the equation x2-8x-4 equals 0?
I'll show work. X2-8x-4=0. X2-8x=4. X-8x=2. -7x=2. X=-(2/7).
What is 8x plus 2 equals - 9 plus 7x?
It's a simple linear equation in 'x'. The 'solution' is the number that 'x' must be, inorder to make it a true statement. There's only one solution. Here's how to find it:8x + 2 = -9 + 7xSubtract 2 from each side:8x = -11 + 7xSubtract 7x from each side:x = -11
What is the answer for 28 equals 8x plus 12-7x?
28=8x+12-7x 28=8x-7x+12 28=x+12 28-12=x+12-12 16=x
8x-2 equals -9 plus 7x?
8x-2 = -9+7x8x-7x = -9+2x=-7
What is x² plus 7x?
7x+x = 8x
