Answer:
Step-by-step explanation:
X + y - Z=3 ------------------(I)
2y + 2z = 6 ------------------(II)
-2y - Z = -2 ------------------(III)
Multiply equation (III) by 2 and add equation (II) & (III)
(II) 2y + 2z = 6
(III)*2 <u>-4y - 2z = -4</u> {Now add and z will be eliminated}
-2y = 2
y = 2/-2
y = -1
Plugin y =-1 in equation (II)
2*(-1) + 2z = 6
-2 + 2z = 6
2z = 6 + 2
2z = 8
z = 8/2
z = 4
Plugin y = -1 & z = 4 in equation(I)
x - 1 - 4 = 3
x - 5 = 3
x = 3 + 5
x = 8
Answer:
3t^3-2t^2
Step-by-step explanation:
Multiply the terms inside the parenthesis by the term outside.
In this case its t.
X=5
Y=1
2x+4(2x-11)=6
+44 both sides
2x+8x=50
10x=50
Divide by 10 both sides
X=5
Plug in 5 to x and you will find y
