You can write the two equations x = 4y - 7 and x + y = 93; substitute the value of x into the other equation
(4y - 7) + y = 93; combine like terms
5y - 7 = 93; add 7 to both sides
5y = 100; divide both sides by 5
y = 20; substitute this value into the other equation
x + 20 = 93
x = 73
So the numbers are 20 and 73
Answer:
32
Step-by-step explanation:
You need to work backwards to solve this equation!
9 - 17 = -8
w / -4 = -8
32 / -4 = -8
Which means that w = 32
Answer:
20.7 --> 21
9.18 --> 9
21x9 is 189, thus the estimated product is 189.
