Answer:
x = 3
Step-by-step explanation:
6x + 2 = 20
6x + 2 - 2 = 20 - 2
Subtraction. Subtract 2 from both sides.
6x/6 = 18/6
x = 3

Answer:
275
Step-by-step explanation:
25x15=375-15=360-85=274
The value of the first 5 is 10 times smaller than the value of the second 5.
You can find this by eliminating each of the other numbers and using 0's in their place.
The first 5 becomes 00,050 or 50. The second 5 becomes 0,500 or 500. Since 50 is 1/10 of 500, we know that it is 10 times smaller.
Step-by-step explanation:
2x - y = 11 -----(1)
x + 3y = -5 ------(2)
By
eliminating "y"
multiple equation 1 by 3 and equation 2 by 1
3×2x - 3y = 3×11
6x - 3y = 33 -----(3)
x + 3y = -5 ------(2)
add eqn (3) and eqn(2)
7x + 0 = 28
7x/7 = 28/7
x = 4
I hope this will help you, good luck!!!
