Answer:
Sorry I don't know
Step-by-step explanation:
Answer:
2y + 7x = -5 (1)
5y – 7x = 12 (2)
Add (1) and (2)
=> 2y+5y +7x-7x = -5+12
<=>7y =7
<=>y=1
=> substitute y into (1) => 2 + 7x = -5
=> 7x =-7 => x =-1
<h3><u>
Answer:</u></h3>
<h3><u>
Step-by-step explanation:</u></h3>
- 2/5(x − 9/10) = −2 3/4
- => 2x/5 - 18/50 = −2 3/4
- => 2x/5 - 18/50 = −11/4
- => 40x/100 - 36/100 = -275/100
- => 40x/100 = -239/100
- => 40x = -239
- => x = -239/40
- => x = -5 39/40
<h3><u>Conclusion:</u></h3>
Hence, x = -5 39/40 is the answer.
