Sam is using the linear equation x-y= -5 to plot a graph. if the y coordinate is 7, what is the value of the x coordinate?

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
