Answer:
a. x=-17, y=27
b. x=0, y=-6
c. x=9, y=-1
d. undefined
e. x=4, y=-6
f. x=4, y=0
Step-by-step explanation:
a. 3x+y=24
y=3x+24
-x+3x+24=-10
2x=-34
x=-17
-(-17)-y=-10
17-y=-10
-y=-27
y=27
b. 3y=-18
y=-6
-6=-x-6
0=x
c. -2x+17=8-x
9=x
y=8-9
y=-1
d. x-7=x+7
x-14=x
-14=0
e. -4x+10+2x=2
-2=-8
x=4
y=-4(4)+10
y=-16+10
y=-6
f. x+2y=4
x=4-2y
-4(4-2y)-3y=16
-16+8y-3y=16
-16+5y=16
5y=0
y=0
x+2(0)=4
x=4
Answer:
multiply 9 from m and -3
9m - 27 + 3m = 7m + 43
12m - 27 = 7m + 43
12m - 7m = 43+ 27
5m = 70 cut 70 by 5 in 14 times [ 14 x 5= 70 ]
m = 14 answer ❤️❤️ it is 100% correct now!
