Answer:
y=-5x+17
Step-by-step explanation:
X + 2y + 3z = 6.....[1]
y + 2z = 0 ...[2]
z = 2 ...[3]
sub in eq [3] into eq [2]
y + 2z = 0
y + 2(2) = 0
y + 4 = 0
y = -4
now sub in -4 for y and 2 for z back into eq [1]
x + 2y + 3z = 6
x + 2(-4) + 3(2) = 6
x - 8 + 6 = 6
x - 2 = 6
x = 6 + 2
x = 8
solution is : (8,-4,2)
The answer to that problem is 2*3/10 which equals 6/10, you never change or multiply or add or subtract, or divide the bottom number
Answer:

Step-by-step explanation:
Answer:
The answer is -48
Step-by-step explanation:
First step is to follow PEMDAS
So we start solving whatever is in the ( )
4^2 is in the ( ) 4^2 = 16 then we multiply
-3 * 16 which is -48
