D because u going to take y6 and y 15 multiples the number it equal to y90 and take x-2 divide into 90
12x - 8y = -12
6x + 4y = -30
Multiply the 2nd equation by 2, to make the Y coefficients opposite:
6x + 4y = -30 x 2 = 12x + 8y = -60
Now add the two equations:
12x -8y = -12 + 12x +8y = -60
= 24x = -72
Divide bothe sides by 24 to solve for x:
x = -72/24
x = -3
Now replace x with -3 in the first equation to solve for y:
12(-3) - 8y = -12
-36 - 8y = -12
Add 36 to each side:
-8y = 24
Divide both sides by -8 to solve for y:
y = 24 / -8
y = -3
X = -3 and y = -3
(-3,-3)
Answer:
X=-4
Step-by-step explanation:
Answer:
steps 4 and 5
Step-by-step explanation:
When we look at example, we can see that we have :
-6r=57
So we divide by -6 and we got
So, our final answer is steps 4 and 5
