Please help me solve this equation is our series mathematical answering article you can find your desire math with easy way, also you can comment for best answer, we will try to published you answer, first of all we have given you a question that is 5x-6x=-17 3x-4y+5z=-1 2z=-6. This is one problem or equation. You just take answer from bellow- Please help me solve this equation
5x - 6x = -17
3x - 4y + 5z = -1
2z = -6
looks like you have 3 equations that have to be solved simultaneously.
looks like your third equation has already solved for z so we can start there.
2z = -6 becomes z = -3 when you divided both sides of the equation by 2.
z = -3 is the value of one of your variables.
you are left with:
5x - 6x = -17
3x - 4y + 5z = -1
that first equation looks like it's all in x so we can solve for x from that equation.
5x - 6x = -17 becomes -x = -17 after you combine like terms.
multiply both sides of this equation by -1 to get:
x = 17
you now have two values out of the 3.
you have:
x = 17
z = -3
you have only one equation left to solve. Please help me solve this equation
that is:
3x - 4y + 5z = -1
replace x with 17 and z with -3 in that equation to get:
3*(17) - 4*y + 5*(-3) = -1
this becomes:
51 - 4*y - 15 = -1
combine like terms to get:
36 - 4*y = -1
add 4*y to both sides of the equation and add 1 to both sides of the equation to get:
36 + 1 = 4*y
combine like terms to get:
37 = 4*y
divide both sides of the equation by 4 to get:
9.25 = y
this is the same as:
y = 9.25
the answer to your equation is:
x = 17
y = 9.25
z = -3
substitute in your original equations to confirm these answers are good.
5x - 6x = -17
3x - 4y + 5z = -1
2z = -6
these become:
5*(17) - 6*(17) = -17
3*(17) - 4*(9.25) + 5*(-3) = -1
2*(-3) = -6
simplify and combine like terms to get:
-17 = -17
51 - 37 - 15 = -1
-6 = -6
simplify further to get:
-17 = -17
-1 = -1
-6 = -6
