I'm so sorry if it's wrong!
There is no following by the ratio of white to red is 5:12 so if you multiply any of those 2 numbers you’ll get it right
Answer: Y = 4, X=4 (4,4)
Step-by-step explanation: You must multiply both equations so the leading coefficient cancels out. I’m multiplying both equations by both coefficients so I multiply the entire first equation by -2 so the first equation will be the negative coefficient and the second equation will be multiplied by positive 9 so the negative and positive equations cancel out.
STEPS IN MATH:
1. (9x-8y=4) -2 = -18x + 16y = -8
(2x-3y=-4)9 = 18x-27y= -36
2. ADD THESE EQUATIONS TOGETHER NOW
-18x+16y=-8
+ 18x-27y=-36
0-11y= -44
-11y=-44
DIVIDE -44 by -11y
The final answer is Y= 4
NOW pick an equation to plug in y to, any equation works
I chose the first one, so 9x-8(4)=4
9x-32=4
9x=36
x=4
Answer:
Add all pounds lost during 3 months. 3+7+4= 14. 4 lbsx4 months =16. 16-14=2. 2 lbs must be lost during the 4 month to stay consistent with the 4 lbs weight loss per month.
