Answer:
x-2x = -3 and x = 3
Step-by-step explanation:
Given the expression
y=x+5.... 1
y-2x=2.... 2
Substituting the first equation into the second we will have;
From 2;
y -2x = 2
x+5-2x = 2
x-2x +5 = 2
x-2x = 2-5
x-2x = -3
-x =-3
x =3
Hence the required equation is x-2x = -3 and x = 3

Answer:
x=2
Step-by-step explanation:
12X2=24+3=27
First, we need to find the GCF (greatest common factor) of each of the number.
1. List out the prime factors of each of them.
2. Multiply the prime factors that the two numbers have in common
60 = 2 × 2 × 3 × 5
84 = 2 × 2 × 3 × 7
The common factors are: 2 and 3
GCF = 2 × 2 ×3
GCF = 12
Factor out 12 from the equation
12(5x - 7)
