Answer:
Step-by-step explanation:
The linear equation in standard form is written in the form :
ax + by = c
Therefore : 12x = -9y + 7 in standard form will be :
12x + 9y = 7
Answer:
1. x = -5 + 5y
2. x = -5 - y/2
Step-by-step explanation:
4(x+2)=4x+8
2(x-1)=2x-2
2(x+1)=2x+2
You use disruptive property when solving equations like this.
