Step-by-step explanation:
.
You want to isolate the variable 'y'.
Subtract 10 to both sides:
Divide -3 to both sides:
Answer:
45/4
Step-by-step explanation:
We can interpret the question to have two equation which can be solve simultaneously
a+b=7------------(1)
a-b=2------------(2)
From eqn(2) make a subject of formula
a=2+b--------(3)
Substitute the (3) into eqn(1)
a+b=7------------(1)
2+b+b=7
2b=7-2
2b=5
b=5/2
From equation (3) substitute value of b to find a
a=2+b--------(3)
a= 2+5/2
a=9/2
Then What is the value of a x b ?
9/2× 5/2
=45/4
Answer:
You can solve one by... it's hard to explain So i'll just show you
Step-by-step explanation:
Here's an example,
2x+7=4+5x
First you subtract the variables on both sides (lower variable)
2x+7=4+5x
-2x -2x
Which will leave you
7=4+3x
The subtract the whole number on each side (lower number)
7=4+3x
-4 -4
Which will leave you
3=+3x
Then you divide on both sides
3/3 3/3
which should leave you
x=1
