Answer:
x is 7 and y is 0
Step-by-step explanation:
So you can replace the x in the first equation:
2*(-6y+7)-9y = 14
distributive law
-12y+14-9y = 14
-21y+14=14
-14
-21y = 0
:(-21)
y = 0
Now you replace the y in the second equation with 0
x = -6*0+7
x = 7
ANSWER: x is 7 and y is 0
Answer:
A. incorrect. He has to divide 76 by 19, instead of subtract 19 to 76.
B. This equation has one solution. v=4
Step-by-step explanation:
Hi, Martin’s answer is incorrect.
A. He has to divide 76 by 19, instead of subtract 19 to 76.
The correct steps are:
19v = 76
Since 19 is multiplying the variable, to eliminate it we have to divide by 19.
v = 76/19
v = 4
B. This equation has one solution. It’s v=4
