Answer:
(4,0)
Step-by-step explanation:
4x+2y=16
-4y+x=4
Multiply the first equation by 2
2(4x+2y)=16*2
8x +4y = 32
Add the 2nd equation
8x +4y = 32
x -4y =4
--------------------
9x =36
Divide each side by 9
9x/9 = 36/9
x=4
Now solve for y
-4y +x =4
-4y +4 = 4
Subtract 4 from each side
-4y +4-4=4-4
-4y =0
Divide by -4
-4y/-4 =0/-4
y=0
(4,0)
Answer:
infinite number of solutions
Step-by-step explanation:
3(4b - 2) = - 6 + 12b ← distribute parenthesis on left side by 3
12b - 6 = 12b - 6
The expressions on both sides are the same
This indicates the equation has an infinite number of solutions
