How do you solve x plus y plus z equals 7 2x plus 3y-z equals -2 5x-6x plus 3z equals 36?
Let me see:1) x + y + z = 7 y = 7 - x- z2) 2x + 3y- z = -23) -x + 3z = 36 x = 3z - 36Subst. 3) into 2):2(3z-36)+3y -z = -2Subst 1) into 3):2(3z-36) +3(7-x-z) - z = -2Subst 3) into 2) again:6z-64 + 3(7-(3z-36) - z) -z = -2z= 67/7Subst answer into 3) -x + 3(67/7) = 36x = -51/7Subst answers into 1):-51/7 + y + 67/7 = 7y = 33/7therefore x = -51/7, y = 33/7, z = 67/7
What is the solve two step equation of -6z plus 16 equals 52?
-6z + 16 = 52 subtract 16 from each side -6z = 36 divide by -6 z = -6
X plus y plus z equals 9 and x plus 2y plus 3z equals 23 and x plus 5y-3Z equals -7 solve for x and y and z?
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
How do you solve this z squared minus 12 plus 36?
z2 - 12 + 36 is the same as z2 + 24. That's a simplification, but not a solution. There's nothing to solve, because the question doesn't give an equation. If z2+24 were equal to something, then we'd have an equation, and we would be thrilled to solve it for the value of 'z'.
How do you solve xyz equals 5 plus z?
You cannot solve one equation in three unknowns. You need three independent equations.
Solve for z z over 12 equals -60?
72
6 plus z equals 3 solve for z?
6+z = 3 z = 3-6 z = -3
Z2 equals x2 plus y2?
What are we solving here for, Z, X, or Y?If solve for Z then the answer would be z = x + yIf solve for X then the answer would be z = z - yIf solve for Y than the answer would y = z - xHope this help.
What the Solve linear equation 1.8z plus 0.3 equals 1.9 z?

How do you solve for x if z equals y divided by x?
To solve for x when z equals y divided by x, you can rearrange the equation to isolate x. Start by multiplying both sides by x to get xz = y. Then, divide both sides by z to solve for x, giving you x = y/z. This is the solution for x when z equals y divided by x.
