<span>2y = x + 3 then x = 2y - 3
5y = x - 7 then x = 5y + 7
so
</span>2y - 3 = 5y + 7
2y - 5y = 7 + 3
-3y = 10
y = -10/3
y = -3 1/3
<span>2y = x + 3
</span>2 (-10/3) = x + 3
-20/3 - 3 =x
-29/3 = x
-9 2/3 =x
or
x = -9 2/3
solutions: x = -9 2/3 and y = -3 1/3
Answer: answer is 0, option A is correct
Step-by-step explanation:
To evaluate the expression,
(5 − 4)0 + (7 − 3)0
Step 1: open the bracket
( 1) 0 + ( 4) 0.....as a mathematical rule, any number multiplied by 0 becomes 0
= 0 + 0 = 0
Step-by-step explanation:
17+7x=x+5
6x=-12
x=-2

B and c
cuz b is has 1/2, which is a fraction that can be placed as 1:2 ratio
cuz c is 4 and can be used as 4/1, which then can be placed as 4:1 ratio
I hope this helps you
