Simplifying
5y + -2 = 4y + 7
Reorder the terms:
-2 + 5y = 4y + 7
Reorder the terms:
-2 + 5y = 7 + 4y
Solving
-2 + 5y = 7 + 4y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-4y' to each side of the equation.
-2 + 5y + -4y = 7 + 4y + -4y
Combine like terms: 5y + -4y = 1y
-2 + 1y = 7 + 4y + -4y
Combine like terms: 4y + -4y = 0
-2 + 1y = 7 + 0
-2 + 1y = 7
Add '2' to each side of the equation.
-2 + 2 + 1y = 7 + 2
Combine like terms: -2 + 2 = 0
0 + 1y = 7 + 2
1y = 7 + 2
Combine like terms: 7 + 2 = 9
1y = 9
Divide each side by '1'.
y = 9
Simplifying
y = 9
Answer:
x.
Step-by-step explanation:
If h(x) is the inverse of f(x) them h(f(x)) = x.
Answer:
24 m
Step-by-step explanation:
the smallest common multiple of 6 and 8.
I know already what that is (24) based on experience, but let's do this formally via prime factoring :
6 ÷ 2 = 3
3 ÷ 2 no
3 ÷ 3 = 1 finished
8 ÷ 2 = 4
4 ÷ 2 = 2
2 ÷ 2 = 1 finished
6 = 2 × 3
8 = 2 × 2 × 2
the smallest common multiple is the combination of the longest streaks per prime factor.
and that is 3 times a 2 and 1 time a 3 :
2 × 2 × 2 × 3 = 24 m
Step-by-step explanation:
given that
let thenumber be x greater than 5
x 5 plus 21
x 26
