3 (horizontally)
I do not think it is easy to explain this answer.
Step-by-step explanation:
2x-y=6 --------(1)
x+y=6 -------(2)
_____ Adding (1) and (2)
3x = 12
x=4
Substitute x on equation (2)
4+y=6
y=2
Answer:
188
Step-by-step explanation:
because you will use cross multiply hours over money
1/12 and 24/m cross multiply 12x24=188
188/1= 188
Use distributive property.
4(m - 2) = 24
Add 8 on both sides to leave the variable on one side.
4m - 8 = 24
+8 +8
Divide 4 on both sides.
4m = 32
---- ------
4 4
You'll get a solution of 8.
m = 8
Check:
4(8 - 2) = 24
32 - 8 = 24
24 = 24
