3x + 2y = 14
Substitute x - 3 in the y spot.
3x + 2(x - 3) = 14
Distribute
3x + 2x - 6 = 14
Combine liked terms
5x - 6 = 14
+6 on both sides
5x = 20
/5 on both sides
x = 4
Substitute x in one of the equations.
y = x - 3
y = 4 - 3
y = 1
Answer:
y = 1
Answer:
0.2
Step-by-step explanation:
An example should help :-
Simplify sqrt 20:-
sqrt 20 = sqrt (4 * 5) = sqrt 4 * sqrt5 = 2 sqrt5
cube root of 54 = cube root 27 * cube root 2 = 3 cube root 2
The rule is to factor the number and look for perfect squares or cubes, etc.
A the answer is 1296 but 756 is squared so it is A ok thats easy i did that in 7th grade finally something i can do
