Answer:
The smaller number is 11
Step-by-step explanation:
The question is
One number is 3 less than a second number. Twice the second number is 16 less than 4 times the first. Find the smaller of two numbers
Let
x and y the numbers
x=y-3 ----> equation A
2y=4x-16 ----> equation B
Substitute equation A in equation B and solve for y
2y=4(y-3)-16
2y=4y-12-16
4y-2y=12+16
2y=28
y=14
x=14-3=11
Answer: x = 8
Step-by-step explanation:
9 ( x - 3 ) = 45
distribute 9
9x - 27 = 45
combine constants
9x = 45 + 27
compute 45 + 27
9x = 72
divide both by 9
9x/9 = 72/9
final answer
x = 8
40/22 would simplify to 20/11
Answer:
"Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.
