3x + (-2x) would be just subtracting 2x from 3x, so it would be 1x or x. Hope this helped<3
Answer:
7/9
Step-by-step explanation:
<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5
1/5x+3y/2=2 => (1/5)x + (3/2)y = 2
Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:
2x + 15y = 20
</span><span>Multiply the 1st equation by -1:
-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.
Solution is (10,0).
The first incorrect is the second step so choice B. ,bc. the exponents need assuming not multiply
