Answer:
x=5, y=6. (5, 6).
Step-by-step explanation:
-6x+6y=6
-6x+3y=-12
---------------
simplify -6x+6y=6 into -x+y=1 and y=1-(-x)=1+x
-6x+3(1+x)=-12
-6x+3+3x=-12
-3x=-12-3
-3x=-15
3x=15
x=15/3
x=5
-6(5)+6y=6
-30+6y=6
6y=6-(-30)
6y=6+30
6y=36
y=36/6
y=6
Answer:
<h3>
-11, -9, -7</h3><h3>
the smallest: 2x+1 = -11</h3>
Step-by-step explanation:
{z - some integer}
2z+1 - the smallest number
7(2z+1) - <u>seven times the smallest number</u>
2z+1+2=2z+3 - the middle number
2z+3+2 = 2z+5 - the largest number
2(2z+5) - <u>twice the largest number</u>
7(2z+1) + 2(2z+5) - the sum of 7 times the smallest and twice the largest
7(2z+1) + 2(2z+5) = -91
14z + 7 + 4z + 10 = -91
-17 -17
18z = -108
÷18 ÷18
z = -6
2z+1 = 2(-6)+1 = -12 + 1 = -11
2z+3 = 2(-6)+3 = -12 + 3 = -9
2z+5 = 2(-6)+5 = -12 + 5 = -7
Answer:
Divide by 7 on both sides
Step-by-step explanation:
7x = 28
To get the variable (x), alone we must divide by 7 on both sides
Value of x: x = 4
Hope this helps :)
(y+3) = −6(x+9) Or y = −6x−57
