Step-by-step explanation:
Step-by-step explanation:
problem 1.
1. 6y = 30
2. y = 5
3. 3x + 2(5) = 16
4. 3x+10=16
5. 3x=6
6. x=2
solution: (2,5)
problem 2.
1. x=7
2. 4(2)-2y=18
3. 28-2y=18
4. -2y= -10
5. y=5
solution (7,5)
problem 3
10x=10
x=1
7(1) +y =-2
y=-9
(1,9)
problem 4
0= -6
no solution
problem 5
0=0
Infinite many
<span>1. 16y = 164 <=> y = 164/16 <=> y = 10.25 or 10 + 1/4. So the answer is a. 2. 8Z = 64 <=> Z = 64/8 <=> Z = 8. So the answer is a. 3. D = ABC <=> C = D/AB. So the answer is c.</span>
