Answer:
y= 1x+6
Step-by-step explanation:
Let's do the sum first:
x+4-8x+10 = x-8x +4+10 = -7x + 14
coefficient is the number beside the x.
so the coefficient for this sum is -7
It is x is less than or equal to -7.
First you subtract -10 from both sides so you will get -2x is greater than or equal to 14 then you divide -2 from both sides so if you multiply or divide a negative number you flip the signs so x is less than or equal to -7.
This is simple division:
So, plug it into your calculator and you get:
Your answer's that
