Answer:
y = -2 x = 0
Step-by-step explanation:
1. 3x-4y = 8
2. 18-5y = 10
Multiply equation 1 by 6
3. 18x-24y = 48
Subtract equation 2 from equation 3
4. -19y = 38
y = 38/-19
y = -2
Sub y = -2 back into equation 1
3x-4(-2) = 8
3x + 8 = 8
3x = 0
x = 0/3
x = 0
Answer:
x=45
Step-by-step explanation:
2x-56=34
Add 56 to both sides
2x-56+56=34+56
Simplify;
2x=90
Divide both sides by 2
2x/2=90/2
Simplify;
x=45
You have to divide 46 by 5. The anwser would be $9.20 for 1 toy .
